Confused about ovulation test results and pregnancy

This is by no means medical research, advice or anything of the like. I just tend to go on internet reading binges, and my husband has no real suggestions or opinions on the matter because he doesn't obsess the way I do sometimes. So I read a few articles about how peeing on an ovulation test can come back positive when you are pregnant because the LH and HcG hormones are so similar and the test cannot distinguish between the two, and you should take a pregnancy test to confirm / deny that you are pregnant. Well I took an ovulation test a few days ago and it said I was at peak ovulation (yay I have only had that twice and I was on medications for the other times). I took another one today and it said I was still at peak ovulation. Now I have questions, has anybody else experienced this or been pregnant and not known because of having PCOS? Can an ovulation test say that you are still at peak ovulation 3 days after the first? How long does peak ovulation last, does anyone know? Should I take a pregnancy test, or am I just getting my hopes up and falling for the myths? I just had a period for a full month, and now it has been almost a month since then. Ugh PCOS, why can't I just have a normal cycle.
