Questions about conceiving after birth control(IUD)

(20F) Hi everyone! My fiancé and I have decided we’d like to start trying for a baby. I’m not looking for advice about if or when we should have kids, so please keep responses on topic.

I took out my IUD about four weeks ago, and I finished my first period three days ago. I typically have a short cycle (around 25 days) and usually menstruate for 4–5 days, but this last period was only about 2.5 days long.

When am I most likely to be able to get pregnant? The internet says after my first period but my friends are saying right after I took my IUD out. Remember the goal is GET pregnant 😊TYIA!
