Cramps

So I had my first transvaginal on Wednesday. I had no idea I was pregnant and went to the hospital. They predicted I am going to be 9 weeks on Monday! But this is my first pregnancy and I have yet to find a gyno due to no health insurance. I have applied for women's health because my job does not offer insurance. My question is, is anyone else having mild cramps as if they will get their period? I'm praying this pregnancy goes well with no problems.
