I know it is hard, but try to stay calm and relaxed and not worry too much. I have had 2 m/c, one at 5 weeks and one at 6 weeks, but never had a watery discharge like you described. Both of my m/c started with very light brownish/pinkish spotting for a couple of days, then bright red spotting, then heavy bleeding with cramps within a few days. I also had the chills. From what my Dr. has told me, some women have bleeding or other discharge during pregnancy, and it doesn't necessarily mean something bad unless the bleeding is heavy or you have bad cramps. You could call your Dr. and see if they will order you a blood test to check your hormone levels. They can see if the levels are normal for your stage of pregnancy, and also if they are rising normally (they're supposed to double every 2 days). That would help you know what is going on and might help put your mind at ease. Good luck. Wishing you the best!
I had a miscarriage a few weeks ago and this doesnt sound like thats whsts happening but to be sure go to the doctors for blood work to test your hcg levels
