7DPO with stuff happening- Belly Button

Hi all, glad i found this board. I am on another board bit noone ever goes there ha. So I feel all alone. I had a MC 2 mo ago and this month we tried again with the works. I am 7 DPO and last ight all night i had pains around my bellow button and below. Ate chicken nuggets at 3:30am (which i would never ever do) and at 7:30 am it was in my throat and i still fell puky, Im more interested in the belly button thing I have a chart of symptoms since 1DPO and my O cramps. Has anyone had belly button issues? This is odd, before my MC i never had this symptom. My temp has been up 7 days in a row still. Thanks so much and MUCH LOVE and baby dust to you all.
