Hi.. I was sexually active on the 12th, 13th, & 18th.. I missed my period following on the 27. Everytime it was unprotected sex but we used the pull out method. During the beginning of this week I had symptoms of back pain, cramps, mood swings, & cravings..I've been sort of having discharge. I then took a 2 HPT on the 1st it showed negative, but I have a feeling I sabotaged both test by holding it under too long and drinking large amounts of liquids before. I then took one before I went to bed and it was negative. All test were on the same day. I took one yesterday, Oct. 4th. It came out negative as well. I just took one when I woke up & it came out negative. Am I pregnant? Why am I late?
