Pregnancy symptoms or in my head?

Kr
I normally get the average range of PMS a week before I start. I've been regular since I had my daughter three years ago but I'm two days late and now my nipples are sore, and my discharge is watery and a lot of it. Hubby and I have been TTC for three months now doing what we are supposed to with tracking, sex, logging, prenatals. Should I test or wait?
