So I'm on progestin only birth control pill  (POPS). But I missed a pill and didn't realize it till about a week later. That was a month ago. Now I missed my period, I'm having cravings, my breast are tender sometimes, and I'm always getting nauseated. But here is the tricky part I took 4 pregnancy test around the time I usually get my period and I ended up with 1 positive, 2 negative, and 1 inconclusive... I'm so confused I don't know... HELP PLEASE!
