Third month trying, here we go!

So I'm in the middle of trying to conceive baby #2! So far, my only symptoms are EW mucus (sorry tmi) but sometimes I get confused because since I've been having sex everyday for the past week, how do I know it's my CM? Ugh, this whole mapping out my cycle is driving me nuts. I'm 31 years old and I am planning to have 3 kids. I'm not getting any younger so this needs to happen now! Lol I have been using pre seed to help the little swimmers out. Hopefully in about 16 days I'll have good news!! Baby dust to everyone!
