So I'm still taking birth control and and am now 6 days late of my period and I took an at home pregnancy test the day I missed and I took it again two days ago and BOTH were negative so what would you do? Should I stop taking my birth control just in case or go get blood work done or just take another test in a few days? My boobs have also been sore and they don't get sore when I have my period only when I was last pregnant. What should I do?
