<s>[INST] Hello.Im 23, female. 60, 250lbs. Im allergic to nothing. Ive had my gallbladder and tonsils removed but other than that Im fairly healthy.I am taking Femara this month for fertility. My worst fear is developing HOS (Hyper-ovulation Syndrome). Today I am suppose to be ovulating and Im having constipation and mild rectal pain. No swelling that I can tell. Just uncomfy, and Im obviously nervous. Nobody ever mentioned pain in my backbone while on Fertility drugs so Im a little unnerved. [/INST] Hello, Welcome to Chat Doctor. Thanks for writing.
