maybe preggers

my body is changing, nothing fits me. my belly has grown very round and poking out. still had a cycle last week but it was a week early and lasted longer than usual. towards the end, I spotted for like two or three days. I am taking a test but not sure which one us the best one to take. has anyone ever gained weight all of sudden around mid section? my husband keeps saying my cheeks in my face is very plumped, hmmmm. I have to wear bigger tops to disguise my belly.
