Hi, i've had really tender breasts for a week and they have grown too (more than usual menstrual tenderness) I had bad diorreah just over 2 months ago and had antibiotics, i'm on birth control pills. Had unprotected sex just after period finished, 2 weeks later I had spotting for a day-was worried I was pregnant but I had my 'normal' pill period that month and last month. Seem to have symptoms tho, breasts hurt, bloated tummy. Does anyone know if it possible to get pregnant on the pill but still have 'pill' periods?
