Ir

Hi all, so my period is almost 3 weeks late I had a positive test 4 days ago, nausea, increased smells, boobs have bright blue veins, head aches, crying like crazy etc. yesterday I wiped it was a bit pink, no biggie accounts to my nurse stepmom. Today I had a bm when I wiped it was pink again. Called ob have appt tomorrow for ultrasound. Now when I wipe it’s brown. I have had two leep surgeries. I have light cramping and tested again and now they are negative. Anyone have this happen and what was the result. I am afraid I am miscarrying
