Hi... I have been on Yaz for the past year or so and recently i decided to get off so that i could lose some weight (gained 20). A couple days after my last active pill, when my period was supposed to start, my husband and i had sex. We used the withdrawl method, but he wasn't sure if any had gone inside at all. However, I started my period the next morning (i think... it was within a day at least). Had a very crampy period, but normal for not being on Yaz. However, that was in late July. It's now almost the middle of august and i've been have these symptoms : Sore tender erect nipples ... sharp cramps in my lower abdomen... and i'm not sure if it's increased tiredness, because i'm always tired... plus my heart burn has been really bad... I have acid reflux (haven't taken my meds in a week or two, just tums) ... Soo.... *deep breath* ... How likely is it that i'm preggo?
