New at TTC

My husband and are a brand new at this, I was previously on birth control pill for the last few months, but I got off of it around 3 months ago and we’ve beeen just using condoms. Now we are ready to start trying to have a baby, just wondering what are signs I should look for...I know it’s best to try during my fertile days. But are their certain positions? Certain things I should or shouldn’t do during sex? We’re just new at this LOL any advice would be appreciated!
