I had the depo shot in may. When it came time to get it again in early August I didn't. I had sex on September 1 and was bleeding slightly. I had figured this to be my normal period. I got my period around October 6 maybe a little before I don't remember the exact date and it lasted until October 9. my period is usually short so I wasn't concerned. I started again today October 14. The blood is thick and dark and it's not enough to cover even a normal sized tampon. I've read a lot of things saying this could mean pregnancy. Anyone know? I've had cramping which is unusual as well as nausea. I've even thrown up twice. Headaches as well as gas. Thanks in advance
