I recently had sex twice, February 6 and February 10, both unprotected. I asked my partner is he ejaculated and he said no both times. He said he pulled out so there should be nothing to worry about. But i got my 'period' but it has been very light

I usually have a heavy flow during this time of the month, even though my partner said he didn't do anything, i am still paranoid about the situation because of the fact that my 'period' isn't normal, and a sigh of pregnancy is spotting in which some women mistaken for a period. I dont know i just need help, i am too young to be raising a child right now.
