OPKs

I started using OPKs this cycle, and for the past three days they have been positive, is this normal?  I thought that it was just three days. I am so confused.

OPKs can be tricky.  It may be perfectly normal that you have 3 positives.  Many women get a few LH surges before the real thing happens.

thank you lady's so very much.  I hope this is our month.

I would also get a + or close to + for 3 days straight. Just keep up with BDing! Lots of baby dust to you****************************

Thanks again for responding.  
I was wondering what you meant when you said I could get a LH surge before the real thing happens. I have been BBT but it has not yet risen so does that mean that i have indeed not O'ed?
