My period came early and I think my boyfriend is jinxing me. Grr

Rachel • a productive human in society.
I wake up this lovely Tuesday morning. Everything is fine. Nothing to complain about, had a cup of coffee, carried out some tasks. 
Now, my boyfriend calls me all worried and flustered because I stress throw up ( my sister has it, mum has it, so it's common in my family. But it stresses him) and he thinks I'm pregnant or might be. But I know I am not because I have been taking my birth control, everyday, right at 9:30pm, also, we use comdoms like 90% of the time.
 Then after an hour, poof, the dreaded cramp. I personally think it's the coffee warning me for the caffeine shits.   But no, it's a PERIOD CRAMP, and oh god. It came with a vengeance. Now I cradle a hot pack to my uterus and have had 2 extra strength Midol and I'm now in a swing of misfortune for my day. I don't know if this has to do with it being a full moon or the fact that my birth control has screwed it up  twice now. Either way.  Pretty sure my boyfriend jinxed my uturis.
