Exactly when I was suppose to have my period. Instead of having my period on vacation I tried to change the date of my period by skipping the 4 white inactive pills in my pack and going straight to the next pack of active ones. However, this has caused me to have a period for longer than I usually do(it's been going for a week). Now I am scared I may of just done something wrong and really messed up my period. Has this happend before to anyone else or can someone give me some advice or clarity on the situation please.
