Odd ovulation...

Jessica • Married to my best friend who is in the United States Coast Guard... Mom to my sonSHINE Anthony, who is 5. Trying for #2
So I am on cycle day 19... Last month I ovulated on CD 22. 
We bd on 3/29 and yesterday, 3/31. Yesterday afternoon I took an ovulation test and the line was much darker, almost as dark as the control line! Today I've taken two ovulation tests and the line is so faint. What do you all think happened? Haven't seen this before!
