Opinions?

It’s 3 days before my period is expected to arrive. Lastnight I had a really odd dream that I was pregnant, this morning I’ve had lots of watery CM, sore and tingly breasts/nipples, slight cramping, back ache, feeling off with foods I usually have no issue with and an aching sensation in my vagina/pelvis. I am confused as to wether this seems to be PMS or pregnancy, I don’t want to get my hopes up but I had sex on each day of my fertile period and ovulation day (confirmed with OPKs) so its the first thing my mind runs to!! Anyone experienced similar and got a BFP? Or do you think I’m looking into it too much! :(
