Your body: is responding normally to not having normal hormonal balance for 8 months. Sometimes this can lead to irregular bleeding for a few months before you become regular again. If you are trying to get pregnant, then you will need to wait for your periods to be regular. If it persists beyond 6 months, go see a healthcare provider to talk about ovulation.
