Itchy

Sara • I have suffered from, battled and kicked the asses of - PCOS, endometrial hyperplasia and endometrial cancer.
Ok this is so weird but I need to know if anyone else had experienced this. So I believe I am roughly 10ish dpo and for about 4 days now o have been uncontrollably itchy all over my body, back, stomach as of yesterday, neck, arms and the worst is the palms of my hands and the soles of my feet. Feet especially at bedtime. The feet were so bad last night they were swollen bright red and covered in hives. Now I do have allergies but this has never happened with an allergic reaction this is something completely new. I have also read recently that itching can be an early sign of pregnancy due to the change in hormones. So I'm just curious about others opinions and if anyone has possibly experience this right before getting their BFP!? As well, yesterday I started  experiencing low pelvic pressure.
