Maternal Milk

I am 13 weeks preggy and my ob gave me Promama as my maternal milk. But everytime na iniinom ko, lagi ako nasusuka and nahihilo. Anyone here has the same experience as mine? Do you think it's one of the syptoms of morning sickness or hindi lang talaga maganda ang lasa ng promama? Sayang naman kasi kung itatapon lang, my ob provided 2 boxes agad.
