Conception after IUD removal?

What are the chances of conceiving if I had sex before my IUD removal? We are now TTC so just trying to get an idea if I should watch for these dates or not!

24th- Had Sex

28th- Had sex in the AM and got IUD out in the PM

If I started watching for symptoms like implantation cramps or spotting, would I track from intercourse date or IUD removal date? Would my chances be better if I have intercourse as soon as possible since I got it out?
