Question

Just have a question for the mommas that have had a miscarriage and then got pregnant after.

I had a great pregnancy October 14 to July 15 and have a beautiful 18 month old. Well I found out July 16 I was pregnant and due March 17 (yes it was planned) well 12 weeks went by and I ended up with a miscarriage on 9/1/16 but baby only measures 8.5 weeks. I told my husband is wanted to wait a few months before we start trying again. Well we started trying again after aunt flo in December and I got a bfp on the 28th ( 3 days before missed period) took another test on the 31st and it said pregnant.

I plan to go to the doctor but should I go and get my levels checked like asap?
