Ended bc after last period, started bleeding 4 days later f/5 days. should start period now, lots of clear discharge instead. pregnant or ovulation?

Not clear: Apologies, it's not clear from your question, where you are at in your cycle. You stopped your birth control after your period, then after your period, 4 days later you had bleeding. This sounds like breakthrough bleeding. Bottom line, if you're worried you could be pregnant, take a home pregnancy test. If you want to be pregnant, have unprotected intercourse.
