Extra cells?

Emmi
I'm 14.3 weeks now but I've been thinking about my last appt at 12 weeks and they told me something I haven't been able to get off my mind. 
They said my Pap smear they did at 10 weeks was a little abnormal and they said something that it was called (I think they did) but basically I had extra cells they found. Told me not to worry about it as far as cancer goes and that it's completely normal for someone my age (I'm 22) and they will recheck in a year after baby is born and things settle down for me. Has anyone else been told this?? 
A little background info..I lost my mom to cancer when I was 17. She had 4 types of cancer one after another for 5 years leading up to her death and the first cancer her had was cervical and then her uterine wall so I'm just so nervous for that fact even tho they said it's completely normal
