TTC Help‼️

I have a 2 1/2 year old who was a surprise , we are now trying for baby #2. But here’s the deal, I was tracking my period up until I got my IUD out since I always got it regularly and lasted 5 days. However, I received my 1st dose of the covid vaccine and it caused my period to go MIA and I missed it by 17days, I got my IUD removed and 2 days later I had my period which ended last night lasting 5 days. Now when should I try having sex, testing etc. I bought Pregmate ovulation tests hoping those would help . I’m so new to this sorry if I sound dumb
