So my boyfriend and I had in unprotected sex on February 18th (which we usually ALWAYS have protected) and we decided it would be best to take a plan b just in case. I have taken like 2 plan b’s before a while ago and really had no side effects at all. But this time about a week after taking the plan b (like the 21st) I had bled for about 3-4 days and it was to where I had to wear and tampon and change it maybe once throughout the day. Which had never happened to me before so that really freaked me out and also I already had my period on the 10th of February. And now I’m feeling bloated now and I’m having like mild cramps and sometimes I do get nauseous but nothing more. Is this normal after taking a plan b?
