I Had Tender Breasts For 2 Wk Before Period, Started

I had tender breasts for 2 wk before period, started period 4 days before missed period according to my calendar, period lasted one full day with clotting then proceeded for a few days of light brown color here and there, took two at home preg tests and said negative, also threw up two days ago mid-day and felt better after, then got sick again last night, also felt better after. All of this has been the last week. Should I see my doctor?
