I am new to ttc so any input would help me.

Okay, my husband and I have been married 15 years we've never used condoms or bc as we have not really tired but if it happend wed be happy. He has a 16 year old already. Well we just now have been ttc seriously. I've been to obg and just recently on July 29th had a biopsy on my cervix. My AF is normal cycle. I have never really had the discharge that everyone says you get when you ovulate. My fertile day was suposed to be last week arroding to this app..but it seems like I started getting more CM on my last "good day" someone said I could be ovulating late, we'll my question is when we have sex,alot of his sperm flows back out always,last night he was out with his buddies and came home showered and we did the BD well nothing really flowed out like normal some yes but not near as much as usual..usually I can still feel it the next morning. Anyone know if it could be bc I'm ovulating late and so there's a chance or am I just dreaming?
