Could I be pregnant??

I came on my period and I bled bright red blood heavily for 2 days and stopped...normally I bleed for 4-5days and then my bloated belly disappears but this time I still feel bloated tired and my clothes feel uncomfortable,I keep having hot flashes and feel nauteos and sometimes I feel fluttering(prob just wind?) I am booked into the Drs but not till 9th may....do I test could I be pregnant or am I just putting weight On??
