I am new to the site, hopefully someone can help. I am 36 and on my first pregnancy. I am on my second IVF cycle, I had my transfer on Feb.1, I took a blood test on 2-15, they say I am pregnant, I am still on progesterone shots, I have been having some light spotting since the transfer, yesterday I had a slightly larger dark brown spot, today, I had another dark brown spot followed by bright red when I wiped, every time I go to the bathroom I get the bright red or pink spotting everytime I wipe. Could this be implantation bleeding? or could I be misscarrying? I still feel tenderness in my breasts and I have had a bad headache all day, does anyone know of any success stories after experiencing these symptoms. Please help, thank you.
