SOS - Birth Control (May be Tmi!!)

I’m on birth control (Depo-Vera) and have been having sex without condom. I’m in the middle of my second Depo shot.

They told me spotting/period change was normal in the first shot (3 months). Right when I got my second shot (early June), all of the bleeding stopped, legit nothing.

Recently (Mid July) I’ve started bleeding again. Regular sex without condom, but after finishing, I start getting cramps and now I’ve started to spot again and my sex drive has been going down. I don’t get my periods anymore and cramping hasn’t been an issue since my first shot (March).

Any idea on why all of this is suddenly happening????

I’m on birth control and even though I am, my partner still pulls out - still a low change of pregnancy. Scared to take a test and the result is wrong. If a gal can help another gal out.
