Mama, any kind of contractions or unusual cramping during pregnancy ay dapat i-check agad ng doctor mo, kahit 2nd trimester pa lang. Hindi ko makakapag-advise ng specific steps para dito kasi it really needs professional assessment. Please message or visit your OB as soon as you can para ma-monitor properly at ma-ease your mind, that's the safest thing to do, okay? Sending you hugs!
