I have had positive OPK's for the past 5 days! (yet to test today!)

On another note this morning I woke up feeling a bit fluee/headachy/cold symptoms. My nose has given me greif all morning. - maybe the first signs of pregnancy, heres hoping!

We didnt BD last night, after 4 nights straight of BD - I needed a break! If I get a postive OPK tonight we will be back "at it" - but a whole 5 days (so far) of positive OPK's has me worried - is it really working?
