No cramps?

Okay so I’m on the birth control pill. I let my boyfriend ejaculate in me every time we have sex.

Ive been on this pill for 3 months now and this week I’m on the withdrawal week. In the past months I’ve start my period on the Thursday of my withdrawal week. I typically get really awful cramps a few days before Thursday. I know that it takes a while for the birth control to become “normal”, but I’m kind of worried about this. My emotions usually go wild after starting this week.

Thoughts?
