trying for a baby after my UID

Hi everyone, so my hubby and I are trying for our second kiddo right now... I had a "period" while I was still on birth control , and the. 5 days after I had my IUD removed I had another.
My question is, how long did it take for you to become able to conceive. 
Right now I'm 3 days late for my period... I'm negative on the pregnancy tests I take so I'm worried I'm not ovulating 😭😭
Please help!! I'm just not sure where to go from here!!
My last baby was a surprise, so this trying for one is quite stressful :/ 
Thankyou!!!
