I went off my birth control pills back in December.. January's cycle was normal, and am trying to calculate conception dates, and then I did not start again until march which as 36 days.. Now its been 41 days and still counting and nothing... I've taken a cheep pregnancy test that was negative.. something that plays a factor is that my husband and I don't have sex regularly, due to work schedules and the cycle I had in march was light compared to previous months. Is my cycle just totally off, or could I be pregnant? Im having frequent urination, and strange sensations in my back, and abdomen..

You can actually still get your period in the first few weeks of being pregnant. Go to your doctor and get a blood test to find out for sure :)
