I'm 5 weeks and for the first time today I had some light pink on the toilet paper after a bowel movement. I didn't think I was straining. No cramping or pain. Just continued nausea with an on and off twinge. Haven't had any more on toilet paper last three times I went. Called doc and she said it could be normal or could be signs of miscarriage and to call if I get period blood. Anybody else have this?? Freaking out
