I got my first shot Feb 12 next April 30th. didn't go back for my next one july16. I took two pregnancy tests in the past 4 weeks bc I have morning sickness every single morning, cramps but no period (had a period every month except this month and I'm a week late), headaches, bloating worst then usual even tho I've been drinking water which stops the bloat, and when I'm pregnant I get the feeling I'm pregnant which is how I feel right now. while the shot was effective I've had sex with my boyfriend no condoms no pulling out but for the past 2-3 weeks we've been pulling out and using condoms. I know it's hard to get pregnant on the shot and usually it makes people unable to have kids at all. plus negative pregnancy tests but I'm still scared. is this normal?
