Heeeeelp/ advice please!

I had my first baby December 25 2019. I really want my second baby to be close in age with my first. I ebf and he sleeps 7-10 hrs a night. I haven’t gotten my period back but I have had stretchy cm. My husband and I have been using a condom but are wanting to start trying for another baby.

Basically I’m just asking for advice or if anyone’s gotten pregnant while ebf & not having their period back yet. Allllso how do I go about starting to use ovulation strips without having my period?
