Pill Fuck Up

I missed the pill on Sunday morning at 5:30am (my fixed time) and so as per advice from other pill users, I took it Sunday when I got home from work at night at 12:30am

So then I was supposed to resume this morning at 5:30 but I took it at 7:45

I’ve been having *SEVERE* cramps all day

Is that normal?

And if I go drinking tonight, will it be safe?
