TMI Blood while number 2

So I'm 16 weeks + 3 days. This afternoon I went to the restroom and went number 2. I am normally constipated and don't go regularly. When I went I looked in the toilet and the water was bright red. When I wiped I noticed a small bright red clot. I was wondering if this has happened to anyone else. If it happens again I plan on going into the ER but I definitely plan on seeing my Doc in the morning.
