Welcome Lisa, and well done J and DL for bringing you here. Our resident preggers gal will, I'm certain, be able to give you some advice, she pops in often, Kate on the OBT, Cake on this.
Yes, if memory serves, she has 4 small children and got through the pregnancies very well except for the last, recent one. Kate is also our resident ketamine expert having been through a few 5-day continuous treatments. So, she's a mine of information....but I'll clear off and make way for others who *do* know something about it!
BTW, although I never had kids (not planned, bad timing and the pill!) I completely understand the ticking clock thing. I finally gave pregnancy a chance at the age of 39 and guess what? Nothing happened

No regrets!
Anyway, great to see you here,
all the best.
