Ok so 2-3 weeks ago one day I thought I was starting my period but it was suuuuper light and only lasted two days and day three I had brown spotting and then day later NOTHING and today 6/8/20 I took a hcg pregnancy test and I saw an super faint line which I’ve never seen before and I need help on recommendation of what test to take and what symptoms to expect
