Hi there. I am on the pill but I had been taking antibiotics and I think I could be pregnant. I have been having some symptoms. My period is due in 4 days and I am still taking the pill I am worried that if I am pregnant I could be harming the baby by taking the birth control pills but I dont want to stop taking the pill if Im not pregnant!! Should I just wait to see if I get my period in 4 days? or should I stop taking the birth control?
