Help!!! Please tell me I'm over reacting.

 Yesterday AM, me and my husband were intimate. Later in the afternoon I noticed a little pink when wiping (less than dime size). I went to the bathroom a few more times that afternoon and nothing. Then in the evening before bed, I wiped, and it was pink again, but this time more(maybe a little more than a nickel). This morning when I woke up, it was a darker red, and I even noticed some in the toilet (like it washed out with my pee) and it was more quarter size Amit on tp. Am I losing the pregnancy? I'm about 5 weeks along. Is this normal? Am I freaking out for nothing?
