I've been so upset since yesterday evening. I've been seriously thinking I'm pregnant, symptoms as - nipple puffiness, nausea, headaches, feeling hungry a lot, even right down to spotting for 2 days. I go to the hospital yesterday to get BLOOD WORK done to see if I'm pregnant or not, the Doctor done a urine test anyways after I said it's probably too early to detect through urine, & I began to tell her all of my symptoms, she said she wasn't sure why I would be doing that, & just checked my thyroids when I already got them checked about 6-7 months back (it was perfectly fine like I told that lady). Anyways, before I even went back to get my blood work down, I read the blood work papers that I'll be getting done, there wasn't no blood work for a pregnancy test but I asked anyways was this blood work done to see if I was pregnant they said yes but I didn't see nothing but a urine pregnancy test down. The doctor was rude to me the whole entire time until she came back to tell me I wasn't pregnant. But there's something in me telling me that I am!
