Pregnancy

So I recently just lost my babies a month ago due to a miscarriage. The doctor told me I’ll be more fertile . My boyfriend and I had sex Atleast 4 times a day since it happened but he doesn’t ejaculate in me . However I didn’t know I was a month pregnant before the miscarriage I just now my stomach felt weird and my nipples felt scabby and bumpy and they were hurting. Now they are scabby and bumpy again , I’ve been nauseous for a few days 3 at most & my nipples aren’t sore . Idk if it could be my period or should I wait until I’m supposed to get my period to take a test .
