My girlfriend and I had sex a day or two after her period. The condom broke and I rushed to the store to buy a plan b pill she took 30 min to an hour after the incident. She started to bleed as if having her period for 4 days even after she just stopped. It's now been about a week or two and she's having light discharge that's brownish and she is having signs of constipation and some weight gain even though she started cross country and its probably muscle mass should we be worried??
