I need Period Info/Help Please?

That's normal, and expect a lot especially within your first few periods. Expect to have heavier flow on the second day/night (prepare for a messy night tonight btw) Also you can expect to change a pad many times a day like you were doing. If you get a chance to change it and might not for a while, change it then. It can leak sometimes so also don't wear anything white or light colored. Also expect very painful cramps at times and bloating. When you are nearing/on your period you can expect that your body might retain water and you may end up gaining up to three pounds of water for the time being (which will then go away once your period is over though). You might also expect to need to take in more food because your body needs the extra nutrients and energy to go through this process, so you might be more hungry than usual.
