Just curious!

My husband and I decided to quit preventing all together and not use any birth control methods. We are not intentionally trying to conceive but just letting things happen. I was monitoring my ovulation as I normally do and I noticed my ovulation tests were coming back as if I wasn’t ovulating as all, very dim lines. Needless to say my husband and I have been quite active the past week and I should have been ovulating. What are the chances that I will become pregnant? Just curious as to all of your thoughts? Thanks everyone! 😀
