Pregnancy symptoms

Question.... I have a two year old but I never had symptoms I only found out I was pregnant with with him at a dr apt for a routine check up and I was almost three months. But me and my boyfriend have been trying and I know I’m too early to tell on a home pregnancy test but I’ve been feeling tired, my boobs are so sore, I’m nauseous with a headache that Tylenol won’t touch, I’m having thick discharge at times but nothing bothersome, and I’m bloated. Is it possible to have symptoms early? I am suppose to get my period in two weeks. 🙈
