Q: My period came 5 days later than usual. What does that mean?
A: A late period could mean one of the following:
1. You did not ovulate (anovulation) in the previous cycle.
2. You did ovulate, but ovulation came later than usual.
3. You did ovulate, you became pregnant, and you had a miscarriage.
Considering your late menstrual period combined with heavy bleeding, it's possible that you were pregnant. There is no way of knowing for sure whether it was a pregnancy or not without a positive pregnancy test. If you do a basal body temperature chart in the next cycle, you can find out what's going on with your ovulation and have a better answer the next time this happens.
