Pg symptoms 3 days after ovulation

Is it possible? Has it happened to anyone ? I don’t usually symptom spot but I ovulated last week, we had sex 3 times during my fertile window and every day since then ivehad cramping in the morning and today. For the past 48 hours my abdomen has been sore. I get a weird sore muscle pain (the kind you get when you’ve done too many sit ups) everytime I yawn, cough or move. I didn’t have symptoms this early with my first so is it possible?
