Shonda • 1 year wedding anniversary April 7, 2014. Ttc baby #1 . Age 27 . This is just the beginning.
I won't give a long out drain story lol I'll just state the facts . 
AF usually comes cycle day 25/26 the latest today is now cycle 37 with BFN. And I've never been before. 
​Got a positive opk April 16 but don't know if it was true since I used Fmu. Most apps think I ovulated April 10 
​Didn't temp during my fertile week because I was on a cruise n totally forgot 
​Here's my chart as of 4/16 . On a regular basis I'm  usually anywhere btw 97 -97.3 
​So what do you think since I'm 11 days and still BFN
