I don't want to get my hopes up!

Ashley

my husband and I have stopped all contraceptives back in March and I got back on a regular cycle about 3 months ago. I am about a week late BUT I had light bleeding for like 5 minutes 2 days ago. I also have started working out everyday which I started 3 weeks ago. could this be just because I am working out and doing way more physical activity? I don't want to get my hopes up so I just need some logically reasoning.
