OHSS While Pregnant

Rachel
Has anyone experienced OHSS during pregnancy? We had our 10 week ultrasound this afternoon and everything looks great (HR is 176bpm!), however my ovaries are STILL very enlarged from <a href="https://glowing.com/glow-fertility-program">IVF</a> on May 7. My doctor thinks it may be mild OHSS so now I need to be monitored more closely. It doesn't sound like there are any risks for the baby, he just wants to ensure it doesn't get worse for me comfort-wise. 
Weird thing is I had no idea as I don't really think I have symptoms. I thought that bloating and some shortness of breath were normal for pregnancy! 
Anyone experience something similar?
