I had spotting as well. I had bright red blood at times. I actually had it from a simple sneeze! It popped a tiny blood vessel on my cervix and it caused bleeding. Its very possible that your bm is the cause. As long as you are not having constant red bleeding things are fine.
As amy stated, bleeding during early pregnancy can be completely normal, but if continues or if it gets worse, I'd go get checked out, it could even be the baby borrowing deeper into the lining, not implantation bleeding, but similar to it. I had the same thing happen at 7weeks with both or my pregnancy. But like I said, if its still happening in the morning or if it gets worse, it can't hurt to get checked.
Hi
Spotting and cramping in Early Preganancy is very normal. If the bleeding is a bright red or you are in alot of pain i would go to the A&E just to be on the safe side so they can check your HCG and cervix to see if its open or closed.
Constipation can also cause bleeding as the bowl is full it rubs on the cervix now your cervix is very tempremental and doesnt like being moved so it can be quite possible.
Good luck and i will keep you in my thoughts
