Negative @ 6weeks? 😢

If I am pregnant, I am getting close to 6 weeks. Cheapies look invalid to me and I got a faint on a Clearblue but I don't trust blue dye. I've heard first response is the best test to take and the most sensitive so I figured it would definitely show, especially if I am this far along but it's just flat out negative. I'm two weeks late and had spotting about a week ago but no cramps or sore boobs.. What's going on 😣 I'm never ever late and I'm not stressed. just a bit frustrated at this point.. this is my first response I took yesterday
