I am 6 wks and I woke up to go pee and I went and wiped and I saw this and I'm freaking out and I can't see the ob til the 11th . Please tell me what is happening . I have no cramps but a small backache and it's not touching my underwear and not going in the toliet . Just please tell me my baby is fine
