Bleeding at 8 weeks

Michelle • 31 yrs old 💜 2nd baby 🤰🏽 Mommy to my princess 👑 another due Nov’2020

I started bleeding this morning. It started off as red. Then now I’m afternoon is lots of brownish blood when I pee. My dr was on lunch when I called but I came to the ER Dept because I have never had this with my first pregnancy.

What could be reasons? Sex? Stress?

Is this normal? Does this happen a lot during first trimester?

Just trying to feel more at ease.
