Ugh pp problems. Got my period for the first time at the beginning of january(12 weeks pp), started my birth control and only took it for a week, if that. Got two more "periods" the last one starting at the end of January and lasted two days. This month so far, no period. Might be pregnant, not sure. We're not opposed to having a baby right now, I'm just annoyed that I don't know what's going on with my body. My periods used to be right on schedule, always. Now it's a guessing game lol.
