Um...wait what?! Help!!

About ten weeks ago I started having symptoms. Two weeks after I took a test and it was negative. I went and found out I was infact pregnant but almost a week later AF showed up and was a lot heavier than normal. What I thought was my miscarriage. Too upset I never saw my doctor and I drank...a lot. Just four weeks ago my mother forced me to get the depo shot. Lately I've been feeling...idk off.

Body aches...especially my back...cravings but not knowing exactly what I'm craving. And big mood swings. My friend brought up pregnancy to me today. She knows about my "miscarriage" but...I'm just lost.
