Should i feel labored just to do normal things? went downstairs to put load of laundry in, my hearts started beating faster, i felt extremely weak, got sweaty and was shakeing i am currently on bactrin for a staff infection, about 4 days now.

Concerning: Palpitations, shortness of breath, weakness, and sweating with minor exertion is a potentially concerning problem. It is not normal. If you haven't seen a doctor for evaluation, you need to as soon as possible. This could be angina, which in women can present without the classic chest pain symptom. Hopefully it's not, but please don't ignore it, get checked!
