Positive OPKs for 4 days!

Natasha • 31yo married
So has anyone every had this happen? I know I probably did ovulate, because it is around the same time each month and I have symptoms that clue me in, but usually the OPKs are positive for no more then 2 days. This month on Clomid 100mg I got 4 days of positive OPKs. Odd? Or normal? And what could it mean? Has anyone had this happen and got a BFP!?!
AF is due New Year's Eve, my husband and I are so excited!! It's been a long 9months of no protection and 3 months since HSG, which def opened up my left tube more and elevated discomfort and pain I had with my month cycles. 
Fingers crossed!!!!
