So by Tuesday of this week, my period was 2 days late

So by Tuesday of this week, my period was 2 days late. I'm never late so I took a pregnancy test. It was negative. I figured I'd start the next day. Well I didn't. My friend told me to wait 5 days and take it again. I waited and was still late. So this morning, Saturday, March 4, I woke up at 6 having to pee. I took a test and watched it, expecting it to say negative. Then this faint second line popped up. So I took another one. Same thing! Two tests say I'm pregnant. I have an appointment to be sure in a week!!!!!
