I have taken 4 pregnancy test the first one was a faint positive, then i took another that night, it was a faint positive. i waited a week then i took 2 more one 3 days ago and it was also a faint positive. one this morning it was positive but once again faint. I know it says not to read the results again after 10 mins but i went back after already reading the positive result after 5 mins. I went back after a couple of hours and the test was showing negitive. I have been having back pain, slight cramping but very mild, and my breast hurt when touched, and I have really bad heart burn and nothing is helping. Whats going on with me. my last period was supposed to be on the 7th of April. it did kind of come but was not normal. I was heavy for about the first half of the day then it was spotty the rest of the day.The next morning was very light and then it stopped again. My fiance and I decided to have sex that night and the next morning I have a couple of spots but nothing after that. My next period should be the 5th of may.
