Late period

layshhh

My period has not shown yet. (3days) late. Since last week I have been having light yellowish discharge that comes and goes . I also had a nose sore that just bleeds and my nose is very dry and then starts like a sinus leak . My breast are very sensitive . I find myself picking at my food cause I can be really hungry and then when I eat I can't . I haven't had any nausea or anything else . But my period should have been showed by now being that I have a normal cycle every month . I didn't track anything this month cause hubby and I decided to stop trying . So idk if I should take a test or not . What yall think might be going on .???
