First sign?

OK so I’ve had extremely sore nipples and sore boobs for eight days now which Ive tried to ignore because so early but I’ve never had my nipples hurt before.

Then today, I’ve had heartburn all day long and I never get heartburn... I literally had to google it to make sure that’s what I was feeling 😂

Has anyone had heartburn as an “early symptom”? I know I’m symptom spotting but I couldn’t help it with the heartburn it’s not going away

I don’t really know how many days past ovulation (first month of not paying attention so no opks) but I do know that my period starts on the eighth it’s very predictable and always on time.

Thank you:)
