pregnant after a tummy tuck

Brittany • Mother of 2 boys( 6/11/08 and 7/4/17) DH had vasectomy, IVF fresh cycle #1 BFP November 2016, Baby born Independence Day 2017, can't wait for baby #3 in a few years! 👶🏽💙❤️💙❤️
Any other mommy currently pregnant or have experienced a pregnancy after having a tummy tuck? I'm currently 29 weeks and my OB stated she can not accurately measure my fundal height due to have thought my stomach is you can feel the uterus. The only upside is my tummy tuck most likely will not be destroyed post-partum and I get to see my baby 4 more times on an ultrasound since they have to do ultrasounds for growth every 2 weeks. I'm also barely showing. I look like I'm 5 months and I'm almost 8. Any input ladies?
