My period was supposed to come on Sunday according to glow. Nothing came except for a little pinkish stain on my pad (I wear them a few days up until my period comes).. That's all that came though, no dark brown coloring like usual. I am not on bc but my fiancé always uses condoms except once or twice but even then he would pull out. Took pregnancy test yesterday night which was negative so I'm sorta confused?? Any input would be appreciated!
