I had my period last week normal lasted for 5 days then the next week i'm bloated and have cramps and spotting?

Irregular Menses: It is common for young women to occasionally have their periods last longer/shorter, come early/late or miss them all together. If you continue to have irregular cycles for 2 more months, see ur clinician for an evaluation. See them asap if u develop excessive bleeding. If u r sexually active, consider hormonal contraception, which can regulate your cycles while preventing unintended pregnancy.
