So last month my period was only like maybe 2 days. Not horrible bleeding but lighter with some small clots. Well now I'm 3 days late for this months period. I took a test, but it came out negative, idk if they aren't good after a while because my friend bought a box with two tests and only used one in the beginning of the year, so could it be a old test? (color on little screen was dark blue, but other was lighter blue) has this happened to anyone before? I know I'm asking like two different questions just need some advice. Thanks!
