Thanks Mamamac

Frustration is an understatement!! We haven't had DH tested yet after all my researching to find somewhere that will do it quickly. We just haven't had the time between, the new house, christmas and visit to my sister in the Uk last week and work is manic for both of us at the moment. We all know we have good and bad days and today is def a bad day, I feel like I am loosing my mind today!! Haven't done stitch of work today just gone daft googling "Have I Ov'd yet!!".
So I have figured the best and worst case scenarios - see if you agree
The situation!!
Tuesday Morning CD14 - Neg OPK
Wednesday Morning CD15 - Neg OPK (DTD that night)
Thursday Morning (8am - fmu) CD16 - Neg OPK
Thursday Night CD16 (10pm) - Pos OPK
Friday Morning CD17 - Neg OPK
(I usually get Pos OPK on CD18 & Ov on CD19 but went back to OPKs after AF arrived 3 days early - which the above now explains why - I've obv started Oving earlier for some reason!)
Worst Case Scenario
I just missed the Surge Thursday morning so say would have got smiley at 10am the min time to ov after that would have been 12 hours so 10pm on Thursday night with the egg lasting a Min of 12 hours bring me to the egg dying at 10am this morning
Best Case Scenario
I had a short Surge starting at 10pm last night to the max ovulation time of 36 hours bring us to 10am Saturday morning and the egg surviving for 24hours bring us to 10am Sunday morning.
So summary is worst case scenario egg died at 10am this morning & Best case Scenario egg won't die until 10am Sunday morning so If we go for the middle I have until 10am tomorrow morning!!!
See told you I was gone batty this morning !!!
I have still have some cramps but def not as bad as they were last night - they kept me awake last night.
