insensitive MIL

Two weeks ago our baby was diagnosed with fetal bladder outlet obstruction. This causes the bladder to fill with fluid but not expel urine. It was discovered at my first ultrasound at 18 weeks that our daughter did not have ANY amniotic fluid surrounding her and her bladder was five times the normal size. We've been seeing a specialist for two weeks. I've had three am amniocentesis procedures...they inserted a needle through my stomach and into the baby's bladder each time to drain the bladder and test for kidney functioning and chromosome abnormalities. Fortunately the kidney functioning is 100 percent and the chromosome count was normal. 
Last Thursday I had a fetal bladder stent inserted. They inserted more needles through my stomach to allow for amniotic fluid and made an incision in my stomach so that they could insert a needle that was loaded with the stent. I felt all of this--the amniocentesis procedures and the stent--which were very painful. Actually, the worst pain of my life. The bladder is draining for now but we go back Thursday to make sure it's still working. 
In the midst of this, we found out we are having a girl. Our first baby. I'm 21w3d. His mother, upon hearing it was a girl, said--"you'll just have to try again for a boy." Really?! We honestly wouldn't care if it's an alien at this point, as long as it's healthy. And the last thing on my mind is trying to conceive again. I felt like slapping her. She's constantly saying "my poor son--having to go through this" and asking me if he's okay. Um...what about me?! I swear, I feel like I'm in the twilight zone. 🙄
