My marriage is on 25th of may so i want to plan my periods early n my last month date was 25 please help me?

Need more info: Assuming you are on birth control pills, you may be able to delay your period by skipping the last week of your pill pack and starting immediately on day 1 of a new pack. The last week a pill pack usually gives the signal to have a period. If you skip the signal, you may be able to avoid a period during this special time. If you are not on the pill, ask the question again with this info.
