Pregnant?

Payton • TTC #2
I miscarried on October 27th. Baby stopped growing at 9 weeks but actually miscarried at 11. I had sex all through what was suppose to be my fertile days. But hard to predict obviously without a period since October... I have been feel nauseous for about 3 days now with a back ache and sore legs... I doubt all of the HCG in my hormones has gone back down to 0 yet but just wondering if it's possible that I'm pregnant again and my hormones are just rising again? I've also been exhausted & napped for over an hour today. Naps aren't usually my thing unless I'm sick or pregnant. Help!!!
