Could I be pregnant?!

So I’m one the pill, my boyfriend and I use condoms. I had sex feb 23, had my period March 2-8, then had sex again March 21, had my period March 30-April 4. I’m wondering cause lately I’ve been upset more, easy for me to cry and just be upset. I’ve had headaches, and recently tummy pains. I have been under lots and lots of stress since February 1st and have been on the go 24/7.
