Hello, My Name Is Ashley Meyerhoff I'm 21 Years Old

Hello, my name is Ashley Meyerhoff I'm 21 years old and I found out I was pregnant two days ago. I've been having period like cramps in my pelvic area and its causing me sharp pain and discomfort. I don't know how far along I am yet but I was wondering if that is normal? My period was suppose to be around this week also so i don't know if I'm just getting the cramps of the period and no bleeding or what it is?
