Hey ladies! 
I'm around 5 weeks pregnant with our first and after sex last night there was a small amount of red blood left in the toilet after urinating.  I was a little freaked out but after calling my doctor today she informed me that it can be normal but put me on pelvic rest until our first ultrasound as a precaution.  Anyone else experience this and get put on pelvic rest?
