If you have been regular with your birth control pills in this cycle, your chances of conception are very minimal. Your symptoms could mean an impending period. To clarify about your status of being pregnant or not, you can get an assessment of the serum beta-hCG
titres now or wait for your next period and go for a HPT 3-7 days later if you miss it. Urinary tract
infections also can lead to similar symptoms of abdominal cramps and hence urinalysis
also is essential in the current scenario. Hope this helps.
