Bleeding and mild cramping day after sex

[zoe2010]

So I'm 6 weeks today. My husband and I had a mini getaway this weekend and had sex twice last night. This morning I woke up and had light bleeding and very mild cramps. The bleeding is more than spotting but not super heavy. But enough to drip into the toilet when I use the restroom. I'm beyond scared and worried. I called the on call doctor and she assured me all is fine and normal, but I still think I'm gonna call tomorrow to see if they can get me in. Did this happen to anyone else??
