post ovulation and having a few symptoms I'm not sure are pregnancy ..

My nipples are super sore I whince at them being touched. aches all over. fatigue .. been needing to sleep in the daytime too.. I slept 10 hours last night and went to zumba this morning at half 9 the same as every Saturday and crashed out for 2 hours when I got home exhausted. on and off mild cramping .. not as noticeable as it was 2 or 3 days ago and the odd twinge. I've attached a photo of my ovia calendar as it shows the fertile dates and when I had intercourse. has anyone had anything similar and gone on to get a BFP? I was in Florida until Wednesday and that night got a positive on an opk so had sex however I wasn't using opk whilst away so I'm not sure how many days it showed positive for
