I had a miscarriage in June and had my regular period again in the middle of July that lasted 5 days. And on August 13th I decided to take a pregnancy test because I had broke up with my boyfriend an wanted to make sure I wasn't pregnant and it came out negative.. we were broken up for about 2 weeks an are back together.. but on the 23 rd I started to bleed what I thought was my period but it was only 1 day and spotting a first pink then brownish.. so today the 31st I took another test an the second line was faint but I can tell its there. I believe I'm pregnant but was wondering how far along I am.. someone help please
