Just once, that's all it takes.

The doctors told me I'm fertile right after the removal so I just wanted to know lol thank you

I just got mine out a few weeks ago, just got done with my period! I bought ovulation strips to help. I also had a two week period after getting my IUD out

You have to know your ovulation date which usually requires waiting a full cycle or 2. When you suspect ovulation its recommended to try e every other day rather than everyday. Hope that helps.
