Itchy boobs, itchy abdomen, before my period that's why i knew i'm going to have period bcoz of this itching.what the reason itchy boobs,itchy abdomen?

Uncommon but happens: The hormonal changes that occur just before and during your period can cause some itching for some women. What I have found helpful for them is have them take a non-sedating antihistamine like claritin, (loratadine) or allegra or zyrtec once a day the week prior to and week of their period. Seems to help. Best of luck with this. Dr R
