I got put on birth control Depo shot in 2010-2011, I got my Last shot March 2018, I started taking the pill in June 2018, I’ve had a regular period since July 2018. I took the pill from June 2018-December 2018. My period was suppose to come February 20th and then February 23rd I had sex that morning when I got off work around 8am , later around 11a-12p I was spotting a light pink color then it got a little heavier around 6pm ( little darker) but not enough to use a tampon. I woke up the next morning and I was much lighter flow & was a brown color. My periods last for 3-4 days this was a 2-3 day thing. I had very little to no cramping but felt nauseous & got dizzy a few times . So I took w pregnancy test (QuickVue) it came up positive, before I got excited I took another one of a another brand( dollar store) and it was negative. I waited a few days took another one ( cvs brand- first response) negative , but I still didn’t feel right , took another one last Wednesday got another positive and felt nauseous to where I could throw up. so I called and made a doctors appointment for March 12th . Then Thursday morning I got another negative. So I have no idea if I’m pregnant or not ! I don’t know if the shot / pill is messing with my hormones or am I pregnant. Has anybody had this issue or heard or anything like this?
