Ok mommy's I have a question. No I have not taken one yet. Could I be pregnant because I feel like my belly (just my belly) looks like it is bigger and where my belly button is I have sharp pains and I can't tell if I have a missed period because I have the implant in my arm. I am scared because I went to the doctor about the sharp pains and the first thing she asked is if I was pregnant and I told her I didn't know but they didn't take a test there. What should I do? Also a couple of weeks ago I got really bad sick and was throwing up and couldn't keep anything down and my boobs are very tender.
