No period

Cataleya

I take cerelle birth control pills, which are progesterone only pills. I was told I wouldn’t receive my period consistently but since starting it in January I’ve not received my period and I’ve had sex twice within those two times, once with a condom, the other time without. I’ve been bloated and getting stomach cramps as though I still receive my cycle. Should I be worried and test myself? I’m 19 btw
