Lynn,
I see. I was on 225 units. It was quite stressful for me towards the end of my stimulation phase. I was supposed to go for my last ultrasound scan on a Saturday, pregnyl on a Sunday, then ER on a Tuesday morning.
On my ultrasound scan on Saturday (that's after 9/10 days of stimulation), of the 10 follicles, only 2 were about 18 mm. The rest were below 16 mm, some even below 10 mm. My doctor decided to schedule another ultrasound scan for me on Monday morning to see if the smaller ones have caught up. Thankfully, they did. By Monday, we had 8 above 18 mm, and 2 were about 16 mm but I was quite worried that weekend whether we would have a good number of eggs for harvesting.
At my review with Angela today, she confirmed that all 10 eggs retrieved were mature but 1 egg could not be fertilised and 1 fertilised abnormally so were discarded.
2 of my embryos that were transferred had fairly thick walls too and as I have never conceived before, CARE decided to do assisted hatching on my embryos. I had been quite worried cause the brochure said it's usually done for women who are 38 and above, who may have lower egg quality. Thankfully, Angela said my eggs were ok.
