Hi Doctor, I am married and since 2 months i see differences in my body and i did not get my period last month also. I have vomiting sensation, morning sickness,very bad back pain, and body pains, i feel my thighs are increasing in size as my jeans has become tight. I went for HPT and its negative. so doctor gave me texakind mf medicine and asked me to use it for 5 days. Can i know the reason behind this
