I was on mini pill for 3 weeks then changed over to noriday mini pill ( had unprotected sex inbetween) i have been on noriday just over 3 weeks but missed alot of my pills. I missed 3 and had a bleed . Ive now been off them nearly 2 weeks had no bleed but feel sick at night, eating alot more, gained weight and i cant even bare water trickling on my boobs. Pregnancy test was negative saturday night??
