I was supposed to take a depo shot in May 2004. I didn't because my husband and I agree that we want more kids. I had no problems in June 2004 or July 2004. In August I started getting nauseated but ignored it. Then I got sore breasts and vomited. MY breasts have been sore ever since but I haven't vomited again. Before I was on depo I had a regular period and extremely healthy and fertile. I have two children already. I started taking depo after my second child. I am having the same symptoms(sore breasts, frequent bathroom trips, nausea, tiredness, sore feet, hiccups, more frequent bowel movements) like I did when I was pregnant with my first two. I took three pregnancy tests. One (first response) had a negative sign. The second (first response) had an almost invisible positive sign, or so It seemed because my husband said he didn't see anything. The third(cheap off brand) said negative. My medical insurance just ended so should I take another home pregnancy test or risk blowing money going to the doctor?
