Please Help!? Can you feel/ think your pregnant while having your period?

Nikki
I have had my regular period every month. But I have also been sexually active with my boyfriend. For the past 2 months [ back to May ] I've been getting some pregnancy symptoms, like: Nauesous, Frequent Urine, More sense of smell, More food intake. Along with that I still have my period. They been coming 4 days late every month along with these symptoms. Right now July 29, I'm Nauesous, and very weak and want to sleep more, and my stomach at certain times feels hard and is growing every week. Now I'm also having my brown to light red discharge that lasted 2 days directly after my period. This month June & July we was more active like 4 times in a month when we usually just have 2 times a month of sexually active. Can I be pregnant and still have my period? Or can I be ovulating early?
