Pregnant with an 11 week old! Help

Kayla

I just had my son 11 weeks ago this coming Tuesday..

well I discovered I’m 4 weeks pregnant, I breastfed on and off so I never had a period. My doctor took my beta and my progesterone is 2.4..

he said it was low so he prescribed me 200mg twice daily.

I’m nervous about miscarriage..

has anyone had this happen before and go on to have a healthy pregnancy? Thoughts??
