S.O.S

So I'm going to try to make this not so long some more people will read it so I can get more help. About 4 months ago I found out I was pregnant. It was unplanned pregnancy with my high school sweetheart we were just hooking up. We went through all the emotions we were going to become parents together and then a little over a month ago I miscarried. I don't want to make him sound like a monster but he definitely wasn't a hero I went through the miscarriage alone. After I had stopped bleeding completely I stupidly hooked up with him a couple more times. This month is the first month I should have started my period again and I didn't. So I took a pregnancy test literally like 10 minutes ago and it says I'm pregnant. I don't know what to do I don't know if I should tell him I need some advice I need some help from my ladies.
