Hey mama, yan talaga ang common sa first trimester kaya hindi ka nag-iisa! A few of us experienced na ganyan, ang ligaments natin nag-stretch para mag-accommodate ng baby, kaya masakit talaga especially pag gumagalaw, at yung bloating at heaviness ay normal din dahil sa hormones at slower digestion. Pero since kasama mo na ang slight vomiting at side pain, mas better na i-check mo with your OB just to be safe and get peace of mind, baka may gas ka lang or it could be something they need to monitor, pero seryoso lang i-confirm with the doc para sure ka. In the meantime, eat small frequent meals, drink lots of water, at try magrest when your tummy feels heavy. Rooting for you!
