<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, I m wondering if I could be pregnant. I m on the birth control pill, and have never missed it or had unprotected sex. However I am having a lot of pregnancy symptoms, and my body feels different recently. I had my last period, but it was very different to normal, it would normally last 5-6 days and I would bleed heavily every day, but this time it only lasted 3 days with very little blood. My symtoms are increased urination, tiredness, nausea, breast tenderness, more prominent veins on breasts and light cramps in lower stomach and back. Please help!  <response>: HI, I understand your concern. Its common with some oral contraceptive pills . To cause side effects having symptoms like yours specially progestin only pills-Mini pills If you are very regular in taking your contraceptive pills did not have unprotected sex . I do not see any chance of pregnancy in your case. Please do not worry. Continue with your pills regularly, it will adjust automatically. TO avoid any stress anxiety. You can repeat pregnancy test after 15 days. When you find that too -ve, you would be convinced. Thanks.
