From my knowledge, it takes between two weeks to a month for birth control pills to be effective, so more than likely, you did ovulate. I take combination pills that thicken my uterus lining and stop ovulation, but even if they only did one of those things, I'd still be protected; if sperm can't get inside you, pregnancy isn't possible, and the same applies if you don't release any eggs. You're just better off taking pills that do both things because it eases your mind and reduces the chance of pregnancy. And you're right about spotting; it's totally normal and it shouldn't happen after your body gets used to the hormones. I wouldn't worry so much about it. After a few months, you'll have full protection of the pills. Just keep in mind that the only way to avoid pregnancy is to stay abstinent, because there have been reports of girls getting pregnant even while on the pill and using condoms. It's rare, but it can happen. As for the cramps, it just depends on your body. I still get them sometimes, and it sucks because you have to be careful about what pain killers you take along with the pill because other drugs can make them less effective. Anti-inflammatory pills like ibuprofen aren't supposed to have an affect on the pill, but I still worry about it.
