Preterm delivery and heart problems.

Ashley
Hey ladies. So I posted a week or 2 ago about being in the hospital for contractions at 31 weeks and having a positive ffn. Well I went in for an ultrasound last Wednesday and both mine and baby's heart rates were up. His was like 170-180 and mine was around 150s so they sent me to labor and delivery to be monitored until they went down. They ended up admitting me to give me antibiotics and fluids because they thought I had a bad infection somewhere. Never found anything. Baby's heart beat went back to normal and mine stayed up. Dr thinks I have some sort of heart problems (runs in both sides of my families) so they kept me for a second night. I was later sent home on a heart monitor(sucks wearing this thing) I was contracting while I was there but they said they weren't worried about it. Ultrasound showed cervix is only 1.8 and I've been dilated 1cm for a long time now. I'm nervous that I'll have complications in labor due to my heart issues. Any advice from you ladies?
