Last week I was 6 weeks and 4 days and I had some brown on the toilet paper when I wiped.

Like almost old blood like after a period. They still got me in and did blood work and a ultrasound. All looked good and the baby had a strong heart beat.

Today I’m 7 weeks 2 days and I wiped and there is more of a red color. What do I do?? Is this normal I’m so worried
