Pregnancy week 4

I just found out I was pregnant and I'm only 4 weeks & 1 day. I had a partial molar pregnancy in late April/early May. I wasn't suppose to be trying to get pregnant to give my body time to "heal" but we did anyways (yes, I know but I needed this to heal I feel like) Anyways, is it bad that I want to wait to have an ultrasound or call my dr till I'm 6 weeks just so I know theirs a heartbeat. (I never heard one last time) & bc I'm a little nervous how my dr is going to react to me already being pregnant.. help & advice please I'm a nervous wreck
