Hi there! So, I am on day 53 of my cycle. My period is “21 days late”, however I have irregular periods. I experienced brown spotting for one day (on the 27th), hardly any at all but just enough to wear a panty liner. I tested a week after my expected period (on the 16th and 19th), both were negative. I just started feeling nauseous today. I’m wondering if these are possibilities of pregnancy or if I’m just having a really weird period?
