Hey ive never posted on here but i really need some help. I know i can be forgetful but this is a whole other deal. 
Im on vacation until sunday (todays thursday) for spring break and I completely forgot my pills at home... what do I do?!?! I realized yesterday that I didnt have them and im confused on what will happen. Will I get my period right away? Will it last super long? Can I start my next pack after my "normal" week when im supossed to get it (im on my first week of the pack right now) HELPP!!!
