Am I pregnant or is my period coming? How to tell the signs apart

The short answer

Many early pregnancy signs feel just like the days before a period: sore breasts, tiredness, mood changes and a bloated feeling. You cannot reliably tell them apart by how you feel. A missed period and a pregnancy test are the clear signs. Most tests work from the first day of a missed period.

Signs that can mean either

The NHS lists these early pregnancy signs, and every one of them can also come before a normal period:

• Sore or larger breasts. The NHS notes they can feel tender “just as they might do before your period”.
• Tiredness, more than usual for what you did that day.
• Mood changes, feeling many different emotions.
• Bloating or a heavy feeling in your lower belly.
• Food cravings or losing interest in food you usually like.

So if you have these a few days before your period is due, they do not tell you much on their own.

Signs that point more towards pregnancy

These are listed by the NHS as early pregnancy signs and are less typical of a normal period:

• A missed period. This is the most common first sign.
• Feeling or being sick, which can happen at any time of day, not only in the morning.
• Needing to pee more often than usual, without pain.
• A metallic taste in your mouth.
• Being sensitive to smells that did not bother you before.
• More vaginal discharge, without itching or soreness.

Early pregnancy signs usually start at around 4 to 6 weeks of pregnancy, counted from the first day of your last period. That is about the time your period would have been due.

What about light bleeding?

Some people have a small bleed or spotting around the time their period is due, and are pregnant. The NHS calls this implantation bleeding: lighter than a period, with only a little blood. A light, short “period” that is very different from your usual one is a reason to take a test.

Signs that point more towards a period

• Your period arrives with your normal flow and lasts your usual number of days.
• The symptoms ease once bleeding starts, which is typical of PMS.
• Your symptoms follow the same pattern as most months.

This is where tracking helps: if sore breasts on day 24 and cramps on day 27 happen every month, they are probably your usual pattern.

When to take a pregnancy test

• From the first day of a missed period, most home tests are reliable.
• If you don’t know when your period is due, test at least 21 days after the last time you had unprotected sex.
• You can use a urine sample from any time of day.
• If the test is negative but your period still hasn’t come, wait a few days and test again. If it is still negative and there is no period, see a doctor or health worker.

A positive result is almost always correct. A negative result is less reliable, mostly when the test is taken too early. See when to take a pregnancy test for more.

When to get help straight away

If you might be pregnant and have bleeding with pain in your belly or one side, pain in the tip of your shoulder, or you feel faint or dizzy, get medical help urgently. Call your local emergency number (in Nepal, 102 for an ambulance).

If the test is positive

Contact a doctor, midwife or health worker to start antenatal care, ideally in the first 12 weeks. You can estimate your due date and weeks with the free due date calculator, or the Nepali (BS) version.

Track your own pattern

Knowing your usual cycle length and symptoms makes a late period easier to spot. Cycella (for ages 13 and up) logs your period and symptoms with no account, and keeps your data on your phone. It is free on Google Play for Android. A paper note or phone calendar works too.
