Kara • Trying for baby #1. Ttc for 1 year.
I took my prenatal vitamin. I check my cm. I put in the info. N I've been taking my bbt for bout 5 days now or so. N it's still saying the same days.. Like the percentage n my fertile window is the same... I don't understand. Isn't it supposed to change when u put in the important info?
