Yes. You can still be ovulating even If you are bleeding. That’s because ovulation cycles can become irregular (because of stress or sickness) and there’s always a chance that you will ovulate right after the end of your period or while you’re still spotting. Since sperm can survive up to five days, that could create a ‘window of opportunity’ for conceiving. You could also experience ovulation spotting, mistaking brownish or reddish cervical fluid with menstruation.
