Can you get pregnant during or right after your period?

The short answer

Yes, you can get pregnant during your period or soon after it. It is less likely than in the middle of your cycle, but it can happen. No day of the cycle is fully safe from pregnancy.

Here is why, in simple words.

Why it can happen

1. Sperm can live for up to five days

After sex, sperm can stay alive inside the body for up to five days. So sex on one day can lead to pregnancy a few days later, if an egg is released in that time.

2. In a short cycle, ovulation comes early

Ovulation is when one of the ovaries releases an egg. It usually happens about 12 to 16 days before your next period. In a 28-day cycle, that is around day 14. Day 1 is the first day of your period.

In a shorter cycle, ovulation comes earlier. In a 21-day cycle, it can come around day 7. If your period lasts five or six days, ovulation may come only a day or two after it ends. Sperm from sex near the end of your period could still be alive then.

3. Ovulation can come early or late in any month

Even if your cycle is usually regular, ovulation can shift by a few days in any month. Stress, illness and changes in weight can all move it. A calculator, an app or a calendar cannot see this change in advance.

4. Some bleeding is not a period

Light bleeding or spotting can happen at other times in the cycle. It is easy to mistake it for a period. Sex on those days can fall in the fertile window.

Bleeding between periods, or after sex, is a reason to see a doctor.

During your period

In the first days of a period, pregnancy is unlikely, because ovulation is usually still some days away. But it is not impossible. The chance is higher towards the end of a period, especially if your cycle is short or your period lasts many days.

Right after your period

The days just after a period are often called "safe". They are not. In a short cycle, these days can fall inside the fertile window. If sperm are still alive when an egg is released, pregnancy can happen.

What is the fertile window?

The fertile window is the five days before ovulation and the day of ovulation itself. These are the days when pregnancy is most likely. The egg lives for about a day after it is released, but sperm can live for up to five days, so the days before ovulation count too.

In a 28-day cycle, ovulation is around day 14, so the fertile window is roughly days 9 to 14. In a 21-day cycle, it moves earlier, to roughly days 2 to 7. That can overlap with the period itself.

Our free period and ovulation calculator estimates your fertile window from the first day of your last period and your usual cycle length. It gives an estimate, not a promise. It works best when your cycle is regular.

Is there a "safe period"?

No. Some people call the days around a period "safe days". But no day of the cycle is fully safe. Ovulation can come early or late, and sperm can live for up to five days. Pregnancy can happen on a day that a calculator, an app or a chart calls "safe".

Safe days are not a method of contraception. Do not use a calculator, an app or a calendar to avoid pregnancy.

If you want to avoid pregnancy

Talk to a doctor or your nearest government health centre about contraception that suits you. Condoms, pills and the copper-T are some of the options, and many are free at government health centres.

If you had sex without contraception and are worried, go to a doctor or health centre as soon as you can. Some options only work if they are taken soon after sex.

If you are trying for a baby

Knowing your fertile window can help. But being in the fertile window is not a promise of pregnancy. Many things play a part, including the health of both partners. If you are planning a pregnancy, talk to a doctor or gynaecologist.

When to see a doctor

  • Your period is late and you could be pregnant. A home pregnancy test from a chemist can tell you, and a doctor can confirm it.
  • You bleed between periods or after sex.
  • Your cycle is often shorter than 21 days or longer than 35 days.
  • Your periods stop for three months and you are not pregnant.
  • You have been trying for a baby for a year without success, or for six months if you are 35 or older.
  • You could be pregnant and have sudden, severe pain in your lower tummy, bleeding or dizziness. Go to a hospital at once.

Questions people ask

Can I get pregnant on the first day of my period?

It is very unlikely, because ovulation is usually many days away. But no day is fully safe, so if you want to avoid pregnancy, use contraception every time.

Can I get pregnant the day after my period ends?

Yes, it is possible, especially if your cycle is short. Sperm can live for up to five days, and in a short cycle ovulation can come soon after a period ends.

Can I get pregnant during my period if my cycle is regular?

It is less likely, but still possible. Even in a regular cycle, ovulation can come early in some months.

Are safe days a method of contraception?

No. No day of the cycle is fully safe. Talk to a doctor or a government health centre about a method that suits you.

Can the period calculator tell me when I cannot get pregnant?

No. Our calculator estimates your fertile window, but it cannot tell you a safe day. Use it to understand your cycle, not to avoid pregnancy.

In short

Pregnancy during or just after a period is less likely, but it can happen. Sperm can live for up to five days, ovulation can come early, and some bleeding is not a period. No day is fully safe, so for contraception, talk to a doctor.
