M 13 weeks 1 day today as per my LMP. From yesterday I am feeling more weakness nd my full body is aching especially near breast and upper back side. My legs too are paining. I last met my OB at 12 weeks for NT Scan. Reports are normal. I told her I was not able to eat anything my entire first trimester. She has given me GRD powder to consume in milk. Prescibed to take thrice since my food intake is low. Also my weight is reduced. Plz suggest. I eat wen I feel hungry but it feels heavy in chest with lot of burps.
