My chart shows I didn’t ovulate but I had a pregnancy test this morning with a very faint line. Is it possible that I ovulated after an LH surge this month but that my temp didn’t rise?

Here’s the poll results

Here’s my chart - I temp at the same time everyday but I have PCOS so my temps are all over the place. A few of the circles are open because I entered my temp after I took it but just later (still took it at the right time though)

My chart does not have three high temps in a row - higher than the previous six temps. I did have a few positive OPKs and lots of EWCM.

Any sight? All comments and thoughts are welcome.
