I've been on the shot for about 6 months. when I got my first shot I was on my period up till my next shot. The doctor said I shouldn't have anymore periods after this shot and I didn't. Me and my boyfriend had sex on the 24th and 25th of August and he came in me. he started having morning sickness and I started having headaches, bloated, tired, feeling like I have to vomit but it never comes out. I have to get my next shot on October 1 ( Tomorrow ) & I've been spotting on and off for 2 - 3 weeks. First it was red then brown then red & brown! I have a horrible cold right now and been having headaches. I took 2 pregnancy test and they both came out negative. Can I still be pregnant? Am I pregnant?
