can anyone help?

So I'm about 8 DPO and was wondering if anyone can shed some light here. 
At 6 DPO I was randomly very lightheaded, most of the day with hot flashes. 
I was doing the dishes and it became so bad I felt like my breathing got shallow and I needed to sit for a while. 
At 7 DPO I was having right pelvic pains. Nothing crazy but enough to notice, along with slightly on the left side. 
Not sure if this can be linked to implantation or not? Early pregnancy symptoms? 
I've been trying for five months.
