Aww, mama, LBM during pregnancy is pretty common kaya don't worry too much, a few of us pregnant moms experienced it din even without eating anything questionable, sometimes it's just hormones or something minor. Definitely reach out to your OB or midwife though kasi they'll want to check if you're staying hydrated and make sure baby's okay, plus they can recommend what's safe to take para sa LBM while pregnant. In the meantime, drink lots of water, coconut water, or broth to keep your fluids up, at try bland foods like congee or bananas if you can tolerate them. Take care of yourself, mama!
