Advice Needed!!

Hi! So my name is Jessemyn, and I'm a 21 year old wife with a beautiful 2 year old son. About a week ago, I got what I thought was my period, except it was lighter than usual and didn't last very long at all (3-4) days. I had the cramps and fatigue and breast soreness, but not like I usually get with my period. I took a pregnancy test about 4 days before I got my period and it came out negative. (Bummer, I know). But ever since my period ended, I've had stringy, partially cloudy discharge. This is accompanied by very mild cramping too!! I have to wear a liner at all times or my underwear feel soaked. Could this possibly be an early sign of pregnancy? I didn't experience this with my son so I'm kind of confused 😂. Any advice is appreciated!!
