Hello. I have recently had ivf icsi, had a fresh day 5 blastocyst transferred 5 days ago. I have ohss difficulty breathing , fluid in abdominal cavity and I am on blood thinners. Last night I started getting a really strong ache in my right arm, shoulder, elbow and wrist, it feels like muscle or bone fatigue. Is this all do with ohss or should I go back to my gp?
