Am I pregnant?

I was supposed to see my period last Monday and up till now, I didn’t see it. I had sex last Sunday, that is, a day to my period. I want to know if with this I can still be pregnant. Please, help me.

• Difficulty in getting pregnant

Anytime you have unprotected sex, there’s a chance of pregnancy — even during your period or right after your period ends. In fact, right after your period, you may be even more likely to get pregnant from unprotected sex because you’ve just started a new menstrual cycle and you could start ovulating at any point. If you want to avoid getting pregnant, use a birth control method like a condom, the pill, the IUD, or the implant. If it’s been fewer than 5 days since you had sex without a condom or another birth control method, you can still use emergency contraception to prevent pregnancy. If not, then you need a Pregnancy test to know whether or not you are pregnant.
