Pink Discharge

jmp2003

So I just got back from the bathroom and I had a light pink discharge. I have read the previous post and most are due to sex or an u/s that day or the day before. I have not done either. I am only 7 weeks pregnant with my third child and this is the first time I have had this happen. I know they say it is normal for this to happen sometimes but of course our natural reaction is to panic. I am currently out of town and the last thing I want to do is run to an emergency room. How long should I wait, or do I wait at all?As I stated before I have not had any type of u/s or heart monitoring done yet, just blood work. I have to wait until the 19th for tall that. Just don't want to overreact and make things worse.
