Been kind of off and on with my BC which I know is bad but I had unprotected sex about a week ago and the other night I had a few drinks. The next morning I woke up to intense cramps really low in my stomach and back left side and began spotting. The blood has gotten a bit heavier and it’s pretty dark. I know it’s too soon to know anything but should I be worried? I’m probably getting myself all worked up over nothing but Google says it can happen within the first few weeks
