Hello, pretty sure I need to try and get the MAP today and I've got a few questions. Will it just trigger a period? And then my cycle changes so in 4 weeks from now I'll have another period or will I have my usual period in 2 weeks like I normally would? Does it mess up your cycle? Can I go to my local GUM clinic (there's one down the road from work) or should I call into a pharmacy and buy it? TIA!
