I am on contraceptive pill for the last 2 yrs.it was prescribed to control my irregular periods & pms. Till now it has worked. Had my last pill on 30.10.12 & started my periods on 4.11.12 which lasted till 7.11.12. I had started taking my regular pills from 7.11.12.had sex without a condom (we always use a condom for double protection.this was the first time without a condom) on 8.11.12 but my pills were on. I am suffering from lower abdominal cramp for a longtime with severe breast tenderness for the last 2 days.no other symptoms.can I be pregnant?what should I do ?should I stop the pills? Just tried some painkillers thinking the cramps would be due to infections... but did not help much

Do not stop any medication without talking to your doctor first.
If you think you could be preganant then taking a test will be the only way to find out.

There are lots of reasons to explain your symptoms other than pregnancy however I think a visit to the doctor will not only put your mind at rest but give you the answer to your question.

Good luck
