hi.I came off the pill over a year ago after being on it for 5 years. im 23. 5 ft 7 and been a steady 15 stone for a while. my periods after the pill were pretty normal and only a few days late etc which i was told was to be expected. i now havent had one for 2 1/2 months. after the first missed one approx 1 - 2 weeks i did a test and it was negative. should i see a docter and what will they do ?
