Cramps on BC?

Aly😽👸🏽
Is birth control suppose to get rid of period cramps? Is it normal to still have cramps even if you're on the pill? I'm on the placebo pills week and am suppose to get my period but I'm not sure if I've gotten it. I have very light spotting and my boyfriend and I have been having unprotected sex, so I'm a little worried...  I'm also having cramps. Is this normal?
