I had an family emergency to where I had to leave Thursday night and drive for 10 hours straight to arrive. I was supposed to start my period Saturday but it didn't start. Sunday (yesterday 3/5) I had one of my top most warning signs my body should get it, whenever I stretch back and all from my belly button down I get a weird pain feeling, and when I get that either later that day or the very next day I get my period. I didn't get it yesterday or today but on the pad it looked to have very very little brownish looking discharge. Not enough to indicate my period has started but still there. What could be going on? Ill also be hearing back home on the 10 hour trip either Tuesday or Wednesday this week. Depending on the results.
