pos opk..... then neg

[lulu_heart]

I got a clear +opk at 8am (not first wee) then i tested again for peace of mind and got a neg opk 6 hours later. Is this normal? Does it just mean the lh surge must have finished? And I should O soon.
I had tested 6pm night before and it was neg.
I guess im asking how long does the lh surge last?

Yes it's totally normal. Some surges last 6 hours and some 24! You will O 12 - 36 hours after first +OPK...it's the first one that counts :wink:
