Strange pinching in left ovary area 4dpo

Today I am 4 days past ovulation and I started getting these little twinges of pain/pinching in my left ovary area. I am also very bloated today and feel like I put on 10lbs this weekend even tho I know I didn't of course. Hubby and I did have unprotected sex on Sunday and Monday and then I ovulated Wednesday. I know for sure I did Wed because it was the most painful ovulation I have had, lots of cramping and pinching. This pain is different though so I'm not sure if I just have gas or what. 4dpo is too early for pregnancy symptoms right? I read online that implantation doesn't occur until 6-12 dpo. Any thoughts??
