I'm so sorry you got a negative result. I know how hard it is to get those.

I did have a triphasic chart once and I wasn't pregnant. Like you, I was so hopeful that it meant that I was, but I just wasn't. Apparently you can have them in pregnant and non pregnant cycles. The same thing also goes for dips that look like they could be implantation dips.

If the temp is a little lower then it's not looking good, but it's not over til AF arrives.

I started to get successful cycles after I cut out transfats from my diet. If you want some info on this PM me & I'll go into detail with you. Apparently too many transfats in the diet of a woman can cause fertility issues.
