Positive OPK?

[KW89]

Hi, it's my first time using OPKs. Been TTC since Sept (miscarried in November)
Is the one second from bottom a positive? The last one seems to be fainter, but not sure if the second last one is dark enough to be positive?
Thanks X

Sorry might help if I actually attach the picture!

Second to last is a clear positive, and the last one also looks to be positive as the lines are the same strength. Based on how dark the second to last one is I would say that was your main LH surge and that you probably ovulated 12-24hrs after you got that one. If the last one was taken the next day that could be the day you were ovulating

Both were taken yesterday, one around lunchtime, the last one in the evening. Husband is on nightshift tonight, did the deed yesterday evening and the night before, fingers crossed that's enough... thanks for replying X
