Bleeding

Today was the fourth time that I had intercourse with my boyfriend, and I lost my virginity to him less than a month ago. I didn't bleed much, but it wasn't only on the first time. I still bleed every time after we have sex but only when I go pee and I notice some spotting, and I still experience some pain in the beginning. Is it normal? Is it possible that my hymen hasn't been completely broken yet? I'm starting to get concerned!
