Bleeding Question?

Sorry for a little TMI... Today after a bowel movement I noticed a little bright red blood on the tissue. I realized it was coming from my vagina. It wasn't a lot. About an hour later I used the bathroom again and it had stopped. I am 6w6d and this is the first time I have had any bleeding. I have a little discomfort which I am blaming on gas. Should I call/go to the doctor or am I worrying too much? My OB wouldn't be able to see me today so I would have to go to walk in care. Any advice would be helpful. Thanks!
