Skin contact rash

Ok ladies, do any of you develop a contact rash after handling something heavy, rough, textured? I first noticed it the weekend before I found out I was pregnant after carrying a burlap bag handle around my wrist. Now if I carry my nieces and nephews on my hip, my arm where it held most of their weight breaks out, and today I opened a jar of jam and my hand broke out. My mom thinks it's contact dermatitis and sensitivity due to all the hormones. The rash only lasts about 10-15 min then goes away. Anyone else get this? A coworker who is also pregnant said she got this when her dogs leash brushed against her leg! So weird!
