So bloated and feeling prego...adter a miscarriage!

I had a miscarriage 3 weeks ago but, my boobs are still super sore and I'm horribly bloated as well as occasional nausea and super tired. I'm hungry all the time too. I'm so confused. I miscarried when I would have ovulated for this cycle so technically AF should be here. I want to take another test but I keep telling myself it can't be possible. What do y'all think
