My period date is 5th march and I am going with my boyfriend on 9th march in delhi. It is very much possible that I get late periods due to which my whole trip will be spoilt. I also have a polycystic in ovary due to which earlier I had very late periods but now from 4 5 months it happening with date just 1 ir 2 weeks late. Which medicine should I take so that they occur 2 weeks after i.e. After 12 march.
