I basicially took plan b after he pulled out and the condom broke .. I was worried something got in me so I went and got the pill. I bled the 3 day after taking the medication for 4 days... I'm having back pains and head aches and I'm scared I might be pregnant or it's paranoia.. Is this normal ??? I took the pill about 3 weeks ago and my perio is due for the 28th.. I just want to know of it is and i have acne aswell which I always get before my period comes
