Period is due Sunday - am I overreacting and worrying for nothing? Advice appreciated!

M

Hi all 👋🏻 my period is due Sunday and I found out I’m pregnant at 9dpo! So 4 days ago now. In June I had a chemical - I found out I was pregnant late in my cycle at 12dpo and the lines were so incredibly faint. I knew that something wasn’t right and this time at present I have a great feeling this baby is sticking around! But I’m so nervous my period will come on time again - I’m experiencing a little cramping - like between implantation cramps and just aches like I need to fart all the time but can’t 🙊 my boobs are so incredibly tender and my lower back in aching all day. I’m also so so tired and experienced a wave of nausea last night! Do you think I’m overreacting about my period? Is anyone else in the same position as me?
