My father passed away on 29th August (I also got my period on 29th which ended on 4th) and I have been very disturbed after that. I had sex on 5th September and took a plan b the same day. My stomach got upset 5 days after taking the pill and I got my period again on 12 September. I am having severe weird kind of cramps since 3 days now. I am confused if all of this is happening due to stress or because of the pill. please guide me?
