Suggestions please?!

Kaley • I just had baby#1 oct 4th 2015(he was my rainbow baby!) and we`re now pregnant with #2!
On September 11th I had a missed miscarriage and was on blood thinners so the doctors wanted me to have an emergency d&c because my body was not natraly letting go of the baby. It has been a month and I have not had my period yet,do you think I should take a pregnancy test? Is it possible to get pregnant right After a d&c?
