Thanks @Bran90
Yes, thank you that makes sense, I understand needing a break in between full cycles, but not between transfers, if the first cycle yields enough quality embryos to do multiple transfers, I don't see why they cannot be transferred month after month. I do not know what my hospitals policy is though, whether they limit it to one frozen transfer or not.
I would recommend doing some research into immune modulating supplements. My husband has autoimmune diseases (luckily he has been very well for a couple of years now) and because of that I did a lot of research at the time into supplements, and there were some studies out there that strongly support them and discuss the science behind it, it's important to look for immune regulating/modulating though not boosting. Most of the recommendations that come up are completely harmless and no doctor would have any qualms about you taking them, but the odd one pops up where there are risks associated so read into it.
I don't have any autoimmune issues that I am aware of, but I did take lactoferrin for a while last year and felt so good while taking it, so I plan to re-start that.
The only reason I mentioned it in regard to fertility, is when I was trying to learn more about the IVF proccess I read a few threads on here with women going through long term infertility, and there were quite a few women surprised to learn in that journey they had autoimmune issues, and steroids/lifestyle changes really helped.
So my thinking is, there is no harm in trying and covering all basis!
