Spotting

Hi! I believe I’m about 5 weeks pregnant with my second. My first pregnancy I only had breast and nipple pain in the first trimester. This morning, I noticed some pink discharge on the toilet paper. A few hours later I have noticed some light red on my toilet paper. I have had some light, intermittent cramps. I’ve been so bloated. I called my OBGYN and can’t get in until the 18th. I explained my symptoms. They said that it could be very normal and to go to ER or call them of bleeding worsens or the cramps. She didn’t seem concerned; however, I have an unsettling feeling. Any advice?
