I've had no sign of my period where usually I have cramps, emotional, sore boobs, and spotting before my period. This month nothing. My period is supposed to start tomorrow but I don't think it's coming. Today I took a first response I had in my car for about a month and it tested positive. I'm just questioning it because it's been hot in my car so it may be a false positive. Anyone ever had this problem? The test isn't expired but I wondering if it just got overheated. IDK HELP!!!
