This might be a dumb or paranoid question coming from a guy, but I'm worried by the fact that my girlfriend is having an abnormal period. She has been on the mini-pill (POP) for almost a year, but usually gets fairly regular periods between 24-30 days that usually last about a week. This month she got it on the earlier side of that range and it was much lighter than normal. Then, on around the seventh day it started getting heavier and I believe is still going (on about day nine). We have sex a few times a week without a backup, and I know firsthand that she ALWAYS takes the pill at the same time every day, but I also know the mini-pill is less effective and this situation has me worried. Could this be a sign of pregnancy? And if yes, could be a sign something is wrong with the pregnancy? I can't really ask her outright because she gets defensive about these things, but it has me nervous. We also started a long-distance vacation that coincided with the start of her period, if that might affect anything. Any insight would really help me right now.
