Tubal ligation 3 years ago, pregnancy symptoms for last week, 2 days late for period (usually early), now extremely light brown (tan) discharge about the size of a dollar coin...I feel off...tired, nauseated, dizzy spells, hungry all the time, change in bowels, gassy, etc. Negative hpt yesterday and today. Not sure what is going on...should I go to ER in case of ectopic pregnancy or wait till Monday and see my obgyn?
