I keep feeling like I am going to get it but it hasn't come.  I am crampy and was really crampy a couple of weeks ago but just figured I was ovulating.  I have been tired, moody and hungry. I've been keeping track on here and the past 3 months I've started within a day of prediction, but this month I haven't started and according to this app I'm 3 days late. we had sex the Oct. 1st so this past Saturday I started having some old blood. I thought it was finally coming and then the "bleeding" stopped until Sunday evening when I started having cramps and old blood again..just enough to tint tp brown..this lasted off and on Monday and now it's completely stopped.. I took a test yesterday and it was negative. I'm br__tfeeding my almost 10 month old son. Is it too soon? is this normal or should I wait a few days and test again?
