Positive pregnancy text this week. According to ovulation I am almost 4 weeks. My husband and I had intercourse tonight and afterwards he noticed I was "bleeding." It was a light pink. Prior to this I had some light brown spotting that lasted about a day, but since then I've had none. Do I need to be concerned? If I don't start to have bright red bleeding am I okay? I was thinking of calling the dr, but I know they won't be able to see anything yet. Thoughts?
