Signs of pregnancy?? Plz read💕

How early have you felt “off” after ovulation?? With my first it was about 12-14 days I felt off but never received a positive until I was 5.5weeks. With my second I swear it was the day after! I then received a positive with him at 8-9dpo. My period is due in 2 days and the morning after ovulation I’ve been feeling off.. I’m 7dpo and I’m getting nauseous in the mornings, my lower back has been on fire, I’m a complete b**** to my husband for absolutely no reason( this is not like me at all😭 even before periods) and I’m exhausted from the time I wake up! Sounds like pregnancy or no??
