Possibly pregnant after a miscarriage?

So early June I had an early set on miscarriage (I was only about 3-4 weeks along) and for the rest of the month my husband and I didn't use any prevention methods. My breasts have been sore for two weeks now, waking up every night to pre for the past week and a half or so, super fatigued, very moody and emotional (my poor hubby lol), acne, heartburn, quweezy throughout the days, dizzy at times, and 4 days late so far. I had a some eggwhite colored mucus a couple days ago and today I had a decent amount of watery substance which has never happened before. I am questioning myself because I am still emotionally getting past the miscarriage and want to.make sure I'm not talking.myself into thinking I'm pregnant. Thoughts? Pregnant or not pregnant?
