Day 20 of my cycle i have brownish red dischage is this implantion bleeding?

Brownish-red discharge around day 20 of your cycle could be a sign of implantation bleeding, especially if you have a regular cycle and are trying to conceive. However, it could also be related to hormonal fluctuations or the onset of your period. If the discharge is light and occurs a few days before your expected period, it might be worth taking a pregnancy test for confirmation. If you have concerns or experience other symptoms, consulting a healthcare professional is advisable.
