Spottings but no period

My period is due today but I am getting brown spotting since three days but no cramps no body pain, feeling very bloated. And uneasy.

How long should I wait ? Does this mean I am pregnant?

Brown spotting generally ends up with period ? If you are pregnant and got brown spotting is it normal ? I had Mc in Jan 2022, so I m worried. Ttc since 3 yrs
