Bleeding during the first trimester?

Kimberly
Hi everyone! This is my second pregnancy and I've experienced some bleeding this first trimester. I got it checked out by my OB and she said I just had to take it easy but that #2 was fine. The issue is that I had sex with my hubby 2 nights ago and I began bleeding bright red blood. Also I was spotting all day long yesterday. My nurse told me I should go to the emergency room if the spotting could soak up a sanitary pad in an hour but it didn't so I never went. Did anybody else go through this? I feel fine but am on edge.
