Wonky Cervix

I had my 2nd BFN on Monday.
Both transfers were very difficult lasting over half an hour. The 1st I suffered lots of bleeding the 2nd I had non but it was still painful and long. It turned out I have a tipped uterus and maybe a wonky cervix.
I saw the R.E on Tuesday and he did another mock transfer. It was painful and long again. He said he got it in once but it was a fluke and when he tried again he couldn’t. He said I need a Hysteroscopy, on the 3/14, to map the uterus and find out the problem. I am very scared. It is so painful when they do the transfer that I’m really worried that is going to hurt. He also said that the reason the embryos are not doing well is due to the traumatic transfer’s. I think my R.E will do Zift on me for with my last 2 embryos. He definitely said something about putting them in surgically. We only have 2 embryos left that are biologically my husbands and mine so I want to give them the best shot. We are not sure if my Dh can under go another MESA to retrieve sperm, we are waiting to hear. If not we will move on to DI/IVF/ICSI with possibly ZIFT.
