AF in 2 days after MC?!

EJane • Boy Mom x2

I had an early Mc in Sep. no surgery needed, my body passed it on its own... we started ttc this month and af is due in 2 days (thursday). Ive been having similar symptoms as my last 2 pregnancies (i have a 1 yr old) any one else on the same cycle? Im scared of another mc due to the cramps ive been having for the past 2 weeks which for my first pregnancy i barely felt, just few days before af was due...
