Is it possible?

I just recently went through a miscarriage (again) but usually I'll wait to have sex until after I have my next period.... well this time i didnt wait, we started having sex immediately after I stopped bleeding from the miscarriage... and I just started having pregnancy symptoms and "feeling" pregnant again!!! I'm crazy... I have to be... is that even possible to get pregnant after a miscarriage. Fairly quickly at that. It's been a few weeks. But like 😳 yall I literally never have pregnancy symptoms like this unless I'm pregnant. It just doesnt happen for me... the only symptom I get right before a period is the crankiness/mood swings... my boobs are hurting, I'm peeing very frequently... my stomach is bottomless!! Now look either the bleeding wasnt a miscarriage at all (never had it confirmed, but it happens very often with me I just assumed....) should I just take another test?? This is seriously blowing my mind right now... this has never happened to me.... 😳

P.s. If that wasnt a miscarriage I would be about 7 or 8 weeks.
