6dpo symptoms

Hey ladies! I ovulated 6 days ago. I know for a fact due to basal body temperature and a positive opk. Anyways, i NEVER get pms symptoms 6dpo its usually too early based on my usual cycle. I have a consistent 34 day cycle so im still about 9 days from my period. I dont typically get symptoms until around 4 days before AF but obviously im not counting out pms as its possible. My fiance and i BD on and around my ovulation day a lot.

For the past 3 days i have felt mildly nauseated at times for no reason. It comes and goes, nothing serious and definitely could be something unrelated. I feel like it most likely is as 3dpo is too soon to feel anything. But now on 6dpo i have extremely mild period cramping. Almost feels like stretching and pulling in my uterus. My back is so stiff and sore. My lower back muscles keep going into spasms. And then my fiance went and grabbed my boobs earlier and i realized my nipples are quite sore. I also recently havent been able to make it through the day without a nap which is weird for me.

Im not looking for advice or anything. Chances are this is most likely just early AF symptoms. But i wanted to document how i feel just in case! Obviously these arent pregnancy symptoms but im wondering if they could be implantation anyone else feel this way at 6dpo?
