Pregnancy calendar ?

Hi ,

I have PCOS and hypothyroidism for which I have been taking metformin and Levothyroxine to keep my levels in check.

I am already 2 days late for my periods. It’s been couple of days I suffered from cold (covid negative). Since yesterday I feel bloated and also nausea this morning. By looking at my calendar, do you guys think I can take a pregnancy test now ? The reason I am asking is based on the timeline if I test now there are chances I might get a false negative as HCG levels might be low ?

Update : tested today, is that a faint vertical line or no line at all ?
