I need help ladies!!

I had a MC on 12/20/15 it was my 5th MC and my 3rd in the second trimestre. I'm writing this on 04/10/16 and till this day I have not stopped bleeding. Some days is very lite and others is very heavy as a regular period. For the past 5-6 day I have been bleeding very heavily and because of that my Hemoglobin levels are very low. I went to my doctor and he sent me for a vaginal ultrasound. While I was getting that done I noticed on the technician that her face completely changed while poking me around and looking at the screen. I asked and she would not say anything and I understood because by law she couldn't. I called my doc the next day to get the results of my ultrasound and instead of telling me something he sent me to get a BETA Test/HCG.

I immediately put a big question face and ask my self why the heck were they sending me to get a blood pregnancy test. I try looking for answers in my head but nothing. I woke up yesterday and thought to my self... "I'm I pregnant" you can imagine how frustrating this is. First I've lost 5 pregnancies already and how the hell did I get pregnant while bleeding (if I was)

I admit that I had unprotected sex with my husband in a couple of times when I was barely bleeding... but to make this story shorter. I got up did a preg test and indeed it was positive.

How the hell did I get pregnant?

Am I having an abortion?

Will the bleeding hurt my baby?

Will I even survive another second trimestre lost??

Im going crazy!!
