First time, doubts

Hi! I had mi first time about a month ago, we used a condom and it did not break, according to my bf. Also he came outside.

Two weeks later I got my period.

I've been very gassy and constipated since my period.

I'm going to take a test soon, but, can I be pregnant? Please, I'm worried

Thanks to all who replied! I feel better. Plus, <a href="">eve</a> says I'm ovulating? maybe that's it. Love you all!

Edit: btw, nobody mentioned anything about the period thing. You can be pregnant and get your period too?
