So I had my day 12 last Friday & the tech told me my lining & uterus looked perfect. I had 2 follicles on the left side & 3 on the right. I had my day 17 yesterday & she said that one on the left side had already collapsed & ovulating & the other follicle was getting ready to release an egg as well. So she told us to go home & BD. She said everything looked perfect. Since I don't have a tube on the right side we are only worrying about the left side but she said everything happened on the left side so things look good. When do I know that I actually ovulated or when will I ovulate? I'm so excited that everything is going in our favor this cycle. I took letrazole this time around & it was my first with that. Next thing they will do is put me on progesterone suppositories as soon as I get a positive if all things go well.
