Hello. So my breast have been swollen and my nipples have been a little sensitive for about a week. My period is always on the 11th of each month but last month it was around the 4th or 5th. This month I started on the 11th again but the blood was light pink at first then spots of dark red and brown. I kept on the same pad all day because it wasnt filling up. The next couple of days it varied. When I peed some red would come out too. Sometimes a little red or dark brown in my pad. I went to see my doctor yesterday and took a pregnancy test and it came out positive. She also had me do a blood test and I have to do another one on Friday. Im just a little concerned because the duration of implantation bleeding is usually 2 days only right? I've read manta rare occasions of them lasting longer. Im just afraid that I could be having an early miscarriage. Im on day 4 bleeding and while it isnt heavy, it also isnt just spotting. I have to keep a pad on . Anybody?
