Everyone said I was experiencing AF and it turns out I'm pregnant

So i kept having weird cramping like AF cramps but they're very light and not painful and it was weird because I'm not supposed to start AF until February 7th. Everyone kept saying it was just early AF symptoms and I went to the doctors today because of it and I told her I was trying to conceive and she said she'll run a urine test. I was nervous because keep in mind im not supposed to start for another week. She came in the room and she was like "so you were trying to conceive" and I told her yeah thinking it was a negative. She shows me the test and she said I'm pregnant. I literally am still shaking and in disbelief. I for sure thought I wasnt able to have a baby and sure enough im pregnant. So I did have a weird period last month and they did a blood test to get an exact idea of how far along i am. So getting the blood work the nurse couldn't get any blood from my vein (I have tiny veins and have to use the butterfly needle which is used for infants and I was really cold) so she took blood from my hand and thats what that green thing is. The second pic is when she came in and gave me the test, first pic is what the test looks like now. Faint but it's there!!!
