Hannah • Me & my SO are actively ttc baby #1 for over 3 years with PCOS and Hydrosalpinx 🤞🏻🙏🏻✨
Okay so AF came 10/31-11/4 37 day cycle I normally have long cycles. Skip ahead to today I wear panty liners because I usually have a lot of cm after af is over well I've noticed a couple time this week light & dark brown discharge not sure why AF isn't expected till 12/9 and yes we didn't use protection no I don't know when we BD. After an unsuccessful year of ttc we decided to try the trying but not preventing method. I need some opinions maybe advice or some stories because I'm at a lost everything I google is coming up implantation. Help!!
