Me and my girlfriend had unprotected sex a year ago after which she took 'unwanted 72'. But after that she started getting irregular periods. She often gets very less quantity of fluid and more than normal stomach ache . But 3-4 times she has got regular periods also. She also has psoriasis and her treatment is always on. Are hormonal changes responsible for this? Or the tablet? Or the psoriasis drugs. But those were there from childhood. Everything started after that pill. Plz help. Thank you.
