What does early pregnancy discharge look like?

I dont know about everyone else but, when I was pregnant (at what must have been 4-5 weeks) it felt like my period was going to come at any time. Kept waiting.... And at about 4 days- 1 week after I had been excpecting my period, I got a positive pregnancy test. In the weeks before, and leading up to this point, I had the same type of cervical mucus you would expect before you got your period. Also my cervix was low for a good week or two (Like my period was coming) before it finally went up and stayed there at about 5 weeks pregnant. From there on I had cervical mucus you would get while you are ovulating or turned on. Also some other symptoms I had that may not be common, but were noticed very early in my pregnancy were;
* An impending feeling of getting your period soon.
* An annoyingly runny nose.
* Bubbly feeling in my stomach, (towards the top by your sternum) kind of like when your really hungry and just drank some really carbonated soda.
* Very tired.
* Irrationally moody and snappy for no obvious reason.
* The general feeling of maybe being pregnant.
* Very thirsty! All the time.
* Having to urinate more often.
* I had slightly sore nipples this time. In the first pregnancy they hurt really bad though. They also feel very heavy and big pretty early on.
Slight skin changes. For example: Breaking out and dry skin early on then nice smooth perfect complexion after about the 7th week on.
