Post transfer ovary pain

Looking for any input from those with experience!

I did an egg retrieval a week ago. Was fairly sore and aching afterwards on both sides. But the Tylenol and heating pad worked great. Felt much better a couple days after.

I did a day 3 fresh transfer 4 days ago. I think the progesterone has made me a little bloated but generally I feel fine. All day today however, my left ovary has been killing me. No sharp pains or cramping. But it’s really throbbing and aching. My right side is totally fine.

Any ideas what this could be? My first thought was possibly a cyst. But it seems like I would have had symptoms several days ago.

Am planning to check in with my clinic tomorrow. But wanted to see if anyone has ever experienced this after a retrieval or transfer.

❤️ thx
