Early Contractions at 19weeks

Hi mga mumsh. How's your pregnancy journey? Kaka check-up ko lang yesterday, oka naman si baby nakita sa ultrasound na gumagalaw yung arms parang nag boboxing. Hehe.. Pero yun nga nakita din na may myometrial contractions ako. Was advised to limit my activities muna at may dagdag na meds for uterine relaxant. I can't help myself na mg worry kc sinabi ni OB if di daw gumana sa sa meds, bed rest ako kc delikado baka mag pre-term labor. ?1st baby namin to at 1 year din kami nagpa fertility workup. Haayy Lord..
