My husband are trying to conceive so hopefully this is a good thing!!  I was supposed to get my period on Friday and it's pretty regular to a 28 day schedule. On Friday I thought it was arriving, when I wiped after I went pee there was red.  Put a tampon in and went about my day. Took it out late in the afternoon - hardly anything on it.  Now today I have a little bit of brown but not my full period by any stretch. Worthy of a pregnancy test or count this as a really light period?
