Help!

Shaney
I stopped taking my bc about a month ago, I had a normal period on it and when I stopped it forced me into another one. That one was about 3 weeks ago. My husband and I have had unprotected sex multiple times since I stopped taking it, and I haven't had a period but have had some cramping. Just like one a day. Idk if I should take a pregnancy test now or wait and see if my period comes.
