miscarriage

Okay, so I got pregnant in November of 2016, and found out January 30th that our sweet bundle of joy didn't have a heart beat any more. 😔 I had to insert pills that made me go into labor because my cervix was still closed and my body wasn't naturally miscarriaging. February 2nd, I gave birth to my child. The next morning I had to have a DNC. It was hard, it's still hard espically now everyone in my family has gotten pregnant since.. I was supposed to have my period 3/4 weeks after but I didn't get my period. Last week, I bled heavy for one day and that was it. Is this normal after a miscarriage? I've also took two pregnancy test to make sure I'm not pregnant again so soon.. and they both came back negative. I'm not sure what's going on with my body and why I only bled for one day. I am scared that I am pregnant again because I've heard if you get pregnant again too soon it will also end in another miscarriage. Anyone else have this issue with your period? Is it normal?
