so confused! Not TTCing. πŸ™‚

Rebecca β€’ I have 2 wonderful boys :) that I love:)

so my period is late by 4 days. it's never late. usually early. I took a test 3 days ago and there was a very very very faint line. I took another 2 days ago and there was nothing. granted I took it at night. but I just don't get it. is it a chemical pregnancy? should I have not taken the second one at night? any advice would be appreciated. I don't have insurance right now so I am worried it's something wrong with my uterus.
