5 days of positive OPKs then negative.

Hi All,

My husband and I are on month 10 of TTC. I take prenatals and he just started taking FertilAid this month. I just had 5 days straight of positive OPK’s and started to get excited because I have read that this could be a sign of pregnancy. However, today I had my first negative test. The line was there, but much more faint than the control. AF is due on the 17th. Anyone have a similar situation? Advice? I know 10 months is nothing compared to some, but man am I getting impatient! Thanks in advance. :)
