Missed period 2 months in a row (usually have reg period). negative hpts. only few pregnancy symptoms. could i be pregnant?

Repeat test in one w: Repeat HPT IN ONE WK. IF STILL NEG AND BREASTS DTILL TENDER MUST Ask Md for pills (provera) to bring on menses otherwise you may bleed so much, change every 15 min for four days! If you already started bleed heavy. Must drink more fluid and eat more salt, otherwise u may be dizzy and very tired. Dramatic wt change recently? Thyroid been tested? Taking new meds? Running too much exercise?
