I am driving myself crazy. I came off of Yaz birth control with the intent to get an IUD in July of this year. I had a regular period a week after quitting. In August, I had a regular period very early on the 7th and then a light 2 day period on the 27th. (No sex occurred during this time from July to the end of Aug). Then, for some reason, on Sept 7th, my husband and I had unprotected sex usuing the stupid "withdrawl" method. (I guess I had a weak moment). 2 days later, Sept. 9th and 10th, I had another 2 day light period and I have had nothing ever since. We have two wonderful children, however I am not ready for a third child just yet - I am working and going to grad school. Does this sound like pregnancy to you or my body regulating itself from the pill? I haven't gotten a test yet since I would only be two weeks pregnant - and I'm not sure if I am ready to read the test result yet anyway. :) Until the pill, my periods have been very normal all my life, starting right on time after having both children. Advice anyone?
