Hi G.
I had in-vitro fertilization to get pregnant and I remember lots of dizzy spells. I think it's the hormones you are on. Try to drink lots of water and exercise if you can. If you don't already, take walks etc. to keep everything circulating.
By the way, after trying Perganol therapy and IUI for months, I got pregnant the first we tried in-vitro.
Good Luck
