Uy mama, while some cramping in pregnancy is normal kaya don't panic, yung consistent feeling na ganyan plus the heaviness sensations mo ay better na iconsult agad sa doctor bukas para ma-ease your mind talaga, lalo na't iba sa experience mo sa first two pregnancies, it's always better safe than sorry! A few of us mum friends nag-experience din ng weird cramping pero different kami lahat, kaya importante talaga na ma-check mo ng doctor para ma-confirm na lahat okay lang with baby at sa iyo. Since wala kang bleeding at laging active pa baby mo, that's a good sign naman, pero yun ang ibibigay ng peace of mind mo, yung actual check-up bukas. Fingers crossed for you, mama!
