4 days late…

I have PCOS but I do get periods every month. I have been taking myo-inositol for over a year and it has really regulated my period. I honestly haven’t been experiencing that many pregnancy symptoms but I have noticed a lot of creamy/egg white consistency discharge and I’ve already experienced this during my “fertile” week so kind of odd but maybe I just haven’t ovulated like I thought. I’ve taken about three pregnancy tests and they are all negative. I’ve been TTC for almost 4 years and have given up honestly but being this late when I haven’t in a long time just messes with me and makes me obsess about being pregnant or not. Has anyone experienced being 4 or more days late with PCOS and ended up getting a later positive?
