Criss

I’ve been ttc this month and since 3dpo I’ve been having the sore heavy boobs that hurt even when you just look at them.....lol I’m now 7dpo and no implantation bleeding or anything but, I’ve been a little tired and boobs still hurt and I’m really gassy.. sorry 😐 and AF starts in 7 days. Could I be pregnant 🤰🏽? I included my calendar 📆
