Listen, I had the third child with no warning of my "window", and almost died from it. I don't want to scare you, but really, really think about this first. My 3rd was difficult from the start. I was diagnosed with a fibroid that was reacting to my horomones and "growing" at the same rate as the baby. I won't scare you with all of my complications, however, my uterus DID rip and apparently the placenta (thankfully) blocked the hole. It must have happened early in the pregnancy, because whenever I had an ultrasound (30 in total) they would always say I really had placent previa. The NEVER diagnosed he abruption. We thankfully chose not to have the recommended amneo. After delivery, my Dr said I would have blead out in less then 2 minutes because there was NO UTERUS holding anything (baby or fibroid) in. only muscle and skin. I know, gross!! When the DR opened me up for delivery 3 weeks early, she said "WOW, I've NEVER SEEN THIS BEFORE!" (really, not what you want to hear). The placenta not only blocked the abruption, but grew throughout my body. It was all over my intestines& abdominal wall, and my bladder was in several pieces. They immediately picked up my very large husband and carried him out of the OR. It took her 6 hours to put me back together, 9 pints of blood and 3 subsequent surgeries. I was in ICU for 10 days. It was apparently very touch and go for a few days. I do not say this to frighten you, but please be aware of the reality. If medical professionals tell you something, you should really listen to the reasoning. It took my 2 years to fully recover (including the eventual hysterectomy at 35 years old). Luckily the baby is now 8 and has a mother and a father. I am really blessed and I know it!! It really could have turned out drastically different. Good luck & God bless.
