Has anyone had this issue? (tmi)

I am 8dpo and OMG I am soo constipated. I maybe had had a bowel movement like 1 time every 3 days.. It's hurting my stomach and causing bladder issues I am drinking lots of water and exercising and I added more fiber to diet but still no change.. I have also had extremely hot face with red cheeks and ear for the past 2 days... Does any of this mean something?
