My last 2 periods were irregular than usual. First I spotted before it came on... It stayed on for 4 days but than it came back on 2days later for about a hour ...weird right !? Then my last period was heavier than usual but after it went off I started having discharge that lasted for about week ...and now it's the 28 of September and I shouldn't be expecting my period until the 17 of October but I been having sharp cramps and nausea
