I'm a 21yo, 1st time soon-to-be-mom. I have Crohn's disease and so my pregnancy is high risk. I've had 2 surgry's related to the Crohn's,have had a few demeral shots due to bad migraines,I have pain that is on the sacrum that feels like it's a pinched sciatic nerve, and my dr. said that in the last ultra sound(profile pic), that I have placenta previa. So I need advice because I'm very worried and I have no idea what to expect.... If anyone has any useful information for me please let me know!!
