My bp rises from 115/80 to 120/90 during my period and then falls back 4 days post period? what should i do, is there sumthing wrong with the harmones

Relax: Excellent that you monitor your B/P. The change you are noticing is a slight variant but normal reflection of the hormonal influences on your blood pressure during your cycle. The diastolic, (second number), is the most important long term and you should seek care if it routinely goes above 90 to 100. Otherwise, eat right, low salt intake, weight management and stress management for now.
