Did anyone have to get testing done 2x a week? My ob said I'm getting a stress test and a ultrasound to check my fluid but my fluid hasn't been leaking or anything do why check? I'm just happy for a weekly ultrasound

Btw Grace is now 4lbs 13oz and I'm having her September 5th at 37 weeks

She's a week ahead and her head is 2 weeks ahead lol
