I'm 22 and started taking Loestrin 24 two weeks ago on the first day of my period. I only enjoyed a few days after my period before I started spotting again, and now it's non-stop. I have also developed acne after a couple of weeks, am experiencing cramping and back/neck pain, and am becoming slightly irritable. I have taken Nordette before and experienced virtually no side-effects. After reading all of these reviews, I am strongly considering getting off this pill.
