When that losing hope feeling creeps in

Char • Mother to one beautiful Son😍
Today is 4 dpo and and a long journey ttc. Yesterday was 3dpo and ovulation was confirmed with Opk and bbt and cm. well on that 3 dpo, I had been feeling very wet (Tmi sorry) and when i went to check it was lots of creamy cm and which was covering a bloop of ewcm. Needless to say I felt like crying as DH has left on a business trip. 
Today 4 dpo, temp drop and I am dry but no I am wondering if my ovulation dates have been wrong both on FF and Glow! 
Any ladies here ever have a similar experience and still had a successful ending?
