abnormal shaped sac??

Kayla
Alright I've been pregnant 4 times and this is the first time I've had a non circular shaped sac. Measuring 7 weeks exactly and there is a heartbeat and a yolk sac. I just need some reassurance that a non circular shaped sac is okay. So ladies post your early sonograms to make this momma calm down. 
This is a pregnancy post miscarriage and after a vasectomy reversal so I'm on edge... help me feel better
