Hey kksquared! I'm sorry to here the witch got you this month! I'm currently waiting for her to show her ugly face! All my preg tests have come back negative, and its not unusual for af to arrive a few days late, (was supposed to me the 11th) so I'm sure she's on her way very soon.
I have been off bcp since July 2014 and we have been ntnp as well. I'm kind of nervous about fertility issues because I have yet to fall preggo. Fingers crossed that's not the problem! I'm pretty sure I've been ovulating later than I thought which could def be the reason.
I currently have the FF app on my phone and LOVE it! As soon as I found out you can do charting and stuff on there I was so excited and went out and bought a bbt thermometer. I've heard bbt charting can get kind of confusing so I'm glad the app does the dirty work for you! I'm also going to be using opk tests. Last month I only used them once per day, and some days I forgot to test!
So this cycle I'm going to be testing twice per day so I don't miss my LH surge!
