Hello, i'm angel.
I'm about 7 weeks pregnant and engaged to the father of my child.

I've been doing extensive research on pregnancy in general, since I have not yet told my mother that i've gotten pregnant. I'm waiting for the right time to tell her, since she hasn't been too happy with me lately already. So i'd rather not make her any more furious than she already is.

Anyways, over the past week or so, i've been having peculiar symptoms:
migrain headaches
dizziness/faint
back aches (which I know are common)
sharp abdominal pains on the lower left section
upper center abdominal pains
insomnia

but out of those five, it's the abdomen pains that worry me. My research has told me that although women who experience ectopic pregnancy (a pregnancy outside of the uterus, usually taken place in the fallopian tubes) do not always have symptoms, those that do tend to have a kind of sharp, uncomfortable pain on the lower part of the abdomen, usually towards one side. It also takes place during the first trimester of the pregnancy. And nothing else I have come up fits that description.

My question is:
even though I do not have the certain history or recent surgeries that are usually required to have a higher risk of having an ectopic pregnancy, is it possible that I could be having an ectopic pregnancy? Or is there another possible explanation? And does me being under 18 effect the chance percentage at all?
