Period after chemical pregnancy?

How long after a chemical pregnancy did your period come back?

I tested positive for a pregnancy test on the day of my missed period, however 2 days later I tested negative. It has now been 9 days since my missed period and I’m getting kind of worried. Tested again today just to be sure and it was negative again.

My husband and I would love to start trying to conceive again but right now we are waiting on pesky Aunt Flow!

Roughly how long does it take to get your period back?

Thoughts? Got a referral to obgyn. Waiting on callback.
