Need some help.

Kelsey • I am 23 years old, I have a 7 year old son and a 4 year old daughter
On April 4th, 2015 I had a miscarriage and I was wondering how long after you have one does your period come? Me and my husband are trying for baby #2 and I have not had my period yet and I would like to know if it will start soon or if I should go ahead and take a test.
