Feeling depressed

#TTC month 5. I got off birth control 5 months ago and didn’t have a period again til last month and now my period is 10 days late so I took a test and it was negative. I’m just feeling really discouraged because I thought I’d get pregnant quick after finally having a period again. I’m also starting to wonder if it was possible that I had a chemical pregnancy and just thought it was my period this last time. Why isn’t my period back on schedule and why haven’t I gotten pregnant yet? I need answers / advice / kind words / anything at this point 😞🤕
