ok my husband and i only use the pull-out method..well my last period was july 9th my cycles are 30 days and wouldve put my period to start on the 7th and about a week after my last period ended i started spotting brown discharge for a week after that..well it didnt start on the 7 and i had no feeling of it coming at all..well monday i took a preg. test around 2:00p.m. and there was a very very and i mean very light blue line like i could only see it in certain lights..it happeneds in like 3 mins and was before the 10 mins so i dont think it was an evaporation line so i took one on tuesday morning and it was the same thing just thinner..well yesterday i felt like i was bleeding (no cramps) and i went to the bathroom and it looked like i had started to spot pink well i ended up started bleeding almost like normal well not as heavy especially for the first day..so i just thought my period was late since it was 5 days...well when i went to change my tampon there was a lot of brown and a lot of clumpy mucus looking stuff(sorry i know its gross) and everytime ive changed it its been this way...im a very heavy bleeder and its not as heavy also i have horrible cramps to where i cant get out of bed and nothing just little cramps here and there..well yesterday i crampeda little worse for about 30 mins..im very confused..i was wondering if maybe this is just a strange period and the line i saw was an evaporation line or it wasnt an evaportation line and i am having a early miscarriage..any advice would be very helpful thanks..
