my period was due this past Sunday the 21st, and I have had no signs of it at all. I tested Tuesday night and it came out negative. my last period was the 19th of December and lasted it's normal 4 days. I had very light bleeding the 4th and 5th. I am on the pill, and my partner and I don't use condoms due to both of us having sensitivity to them (both latex&latexfree;). should I test again?
