Pregnant again?

So I was 8 1/2 weeka pregnant and I miscarried on Christmas day, I only bled for 2 days and doctors confirmed my levels dropped. 4 days after my miscarriage my SO decided he'd ejaculate in me again. And just the last 2 days I've been having symptoms similar to the first time before I found out. These symptoms occurred before then went away. Last time I ate nachos and immediately after I was dry heaving and then throwing up, I have added discharge, the big thing is I had pressure on my left side alot lát time and it just came back lastnight (and no its not due to constipation) and I am overly emotional again like bawling over stupid stuff, and my nipples are back to being sensitive. Please help me do you think I am?
