Do you have any symptoms?I mean if your still getting your period and you dont have any other symptoms then your probably safe.

Pulling out isn't as effective as a condum. There is a chance you can get pg with pre ejaculation so really if you miss a period, or have dark red, or brownish periods and really illregullar. And other syptoms of being pg then you could be but if your not having any other syptoms you more then likely are not.

Sometimes if a girl has sex close to the time of her next explected period she will actually go ahead and have that period but then miss the next
i doubt you're pregnant because you said your period was regular
but do you have any symptoms

Me and my husband have been trying to have a baby well, before my period was due i started having all the symptoms but then i ended up having my period 2days late and they were nothing like my normal ones, it started off lightly and it was brown then by the end of the day it got heavy, but then by the next day it was red. but it was off and on the whole time. but i dont know what could be causing it. but i dont know if i should have but i took a test the 3rd day of what i think was my period ( not for sure) and it came out neg, but i dont know if it was right. can you take a test while on your period??
