Need advice

Hi everyone. I stink at postpartum charting.

I'm pretty sure I know the answer, but can someone confirm?

I'm 36, and my husband and I are done having kids. :( I'm 11months postpartum and still nursing.

Well, I temp and track LH. I am anovulatory to date. You can't ovulate and NOT get a period right?? Last week was the first time hubs and I had unprotected sex since baby (he is actively TTA). All my LH tests had been negative and my temp was down so I assumed it was safe-ish. The next day I had a blazing positive OPK and gobs of EWCM. Unfortunately, it really got my hopes up...

Anyway, this past weekend I was sick and had a slight fever, and I think that's why FF thinks I ovulated.

What I'm asking - there is no chance of pregnancy with temps as low as my chart shows, correct? Looking at past charts (I have 4 kids), my temp always has risen to around 98 degrees when pregnant.

Thanks for the help. Guess I'm just a sucker hopeful for an oopsies baby that likely isn't possible at this point.
