Discharge and symptoms.....

So I'm posting this to try to get some reassurance until my ultrasound next Thursday and hoping you ladies could help.

My husband and I suffered a miscarriage back on May 24,17 and ever since I got my BFP almost 2 weeks ago I've been paranoid and worried and analyzing everything. This is our 3rd pregnancy and 2nd baby.

I had nausea with my daughter but no vomiting. This time around not as much, I'm only interested in salty foods lately and no sweets.

This may be too Tmi but I have a lot of white milky clear discharge is this a good sign of a healthy pregnancy? Question being just because I don't have a ton of pregnancy symptoms doesn't mean I should worry right?

TIA
