Hi. I think I might be pregnant but I dont know. I was on the birth control shot for about a year. I recently anout a month or two ago switched to the pill. I haven't been taken them at the right time but I have been taking them. Last year I was on the shot for 9 months and then switched to the pill. I had the same problem with taking the pill and I ended up pregnant. I didn't know because I didn't have any symptoms except for a missed period. My last period was september 23. I had sex the 8th of october. I started spotting but only for two days. It was kind of brownish and light pink. I took a test but was negative. Maybe I tested to early. Anyway my doctor told me to wait until my period was due. Well my period hasn't come yet. I been feeling nausea and my stomache feels funny. Also lately my lower back has had alittle pain off and on. I have lost my appetite for things that I alwasys ate. I took a blood test yesterday and are waiting for the results. I have been trying to eat rigth just in case... Could I be pregnant and has anyone had this problem before and was pregnant??? Im 19
