What do you think? Pregnancy or something else?

Hi! So, I had my period on the 13th of June and it lasted about 4 or 5 days. I did have unprotected sex during my period and he did finish inside me. Now I didnt stop bleeding after intercourse. Then we had sex around the 23 or 24 and used the pull out method, last night however we had unprotected sex and he did finish in side me, and this morning i wokr up bleeding, not like a period bleeding, but enough to get in my underwear. What do you think is wrong? I know this cant be implantion bleeding because its more blood than that...any ideas or advace is appreciated. Thank you in advance.
