Hello.I stopped BC pills on Nov 6 2005 the Sunday during my period. Since have gotten periods, but not always same time. Longest was 6 and 3/4 weeks apart, shortest was 4 weeks and 2 days apart (which was last "normal" period-got on June 27). They usually last 3-5 days since stopped pills. I believe I was ovulating on 7/12.Had unprotected sex on 7/13. About a week later I was feeling slight cramping in my lower abdomen and slightly bloated like I couldn't hold in my stomach. I was "due" to start my period on 7/25 and thought I was getting it-had cramps, but never came. On 7/26 I thought I had a hot flash and I felt nauseous in PM (although I was painting a room at the time). On 7/27 I felt a belly button twinge in afternoon and in PM I had tiny amount of clear mucous with brown/red blood in it when I wiped. Next day same, but more brownish in color. My back also hurt and I had cramps, bloating. Nothing the next two days. On 7/31 I was crampy in lower ab and had tiny amount of fresh tinged red mucous in AM when wiped. 8/1 tiny amount of red/brown mucous on tp in AM, same on 8/2. On 8/3 still seeing small dark red blood/mucous on tp in AM, and felt slightly queasy and gassy (burped alot in AM) and tired. 8/4 same. Took HPT(EPT)in PM on 8/4-negative. 8/5 no spotting in AM, cramps became heavier and soiled underwear in PM. Cramps all night. When woke in AM 8/6 large blood clot when wiped, thought period started. 8/7 heavy bleeding in AM, very light in PM, tired. 8/8 was pretty much gone.Today 8/9 I have bloated, crampy feeling in lower ab and back pain, tired. Am I pregnant?
