I posted on here a few weeks ago about having really bad cramps but they felt different not like regular cramps and would come and go like contractions. If that makes sense. Well it’s been more than a month since I last had sex and after the two weeks of having sex I took the test because something was just off I could just tell but the test came back negative but lately I’ve been feeling very fatigue, tired, and nauseas. At first I thought okay the nausea is because I suffer from migraines but I get nauseas even when I don’t have them. I’ve also been getting stomach pain and thought I should take my nexium for the slight gastritis that was found in May but that didn’t even help.

I told a friend and she said I should take a test should I ?

Keep in mind when I had sex I was on the depo but later the next day I took my barbiturates for my head ache that I was having but did not realize that the barbiturates counters the depo shot. Since sperm lives inside the body for up to 7 days is what made me take the test but came back negative. But now since the third week there have been new symptoms should I seriously take a test ?
