Are my symptoms pointing to pregnancy????

Hey! First post/question. Af is due on Wednesday and for the past week or so I've been experiencing cramping just on my right side, which never happens. Really irritable and emotional. But oddly enough, no sore boobs, which I usually have before Af. TTC for only one cycle and I'm 12 dpo/BD. I thought I had implantation bleeding on 8/22, a little light pink dot, but figured that was too early according to some of the info I've come across. Thoughts? I def feel...weird/different than usual.
