I'm guessing it's the endometrin that's causing it but it comes on suddenly and I feel like I just got off a merry-go-round. I remember having dizziness when I was on crinone and some, the last two IVF attempts, with endometrin but not like this. My eyes are also super irritated and red and my memory is shot. DS told me the other night "Mommy I don't like the red cracks in your eyes!" Let's just say I hate side effects! Chat Icon
