Clomid side effects

Natarsha • Been trying for baby #1 since June 2014 .. I have a blocked right side. IVF started April 2016
Did anyone else have side effects using clomid. Been trying 17 months. First month on clomid... Estrogen tripled in number and I got the needle on day 11 to release my
Egg. Nope hope this month as I only had an egg on right side (blocked side 😢) I was on clomid days 3-7 . I'm currently on day 17 of my cycle 5/6dpo . I have been getting cramps/ feeling off . Could this be because my estrogen levels are going down (they have never been this high on ovulation) so thinking my body is not use to this? Anyone have side effects on end of cycle?
