TTC TIP.. I had no idea

This may be obvious but I had no clue. My husband and I have been trying for 8 months and of course every month I’ve been so disappointed. I read online that the lube you use could greatly decrease chances of conceiving. Turns out one of the first ones on the list was the one we were using. My last cycle we did not use lube. A few days ago I got a very faint positive test. I have not confirmed yet with a blood test but I will update if it turns out this is my positive!! I just wanted to let you ladies know just in case you were clueless about this like I was!
