Need some advice

Jordan • Eliana Rose ♡ 03/24
At around cd43, 17 days late. lmp was March 10th so I completely skipped this month. I think O was late, either March 31st or April 2nd. Actively ttc and have had plenty of symptoms!!! Excessive sticky egg white discharge, "waves of morning sickness", fatigue, it varies on the day. Obviously a missed period, and all negative hpt's !!!! So frustrating. I'm estimating around 5w3d due date 12/24/15.. Anyone have anything they can share?? Could I still be pregnant this late and just not be showing up on hpt
