Day 8 and counting...

Taylor

Something is very off about my cycle. usually my period only lasts for about 3 to 5 days. ive been like that since i first started. yeah lucky me lol. problem is now im going on day 8 with no sign of slowing down. its the holidays so my ob isnt even in to contact so im wondering how often do you guys experience random sudden changes like this? is it usually something to be worried about?
