natatakot ako mga mommies!!! ?

SKL experience ko just today. I reported to my work yesterday Feb 17 2020. My day was really fine or maybe I am just so excited coz finally after more than 2 months from bedrest back to work n ulit ako. That feeling was so normal. Then afternoon nkaramdam ako ng sakit s puson or mabigat n puson. Nakauwi pa ko s bahay just by walking. And today, again I am enjoying working pero afternoon heto na naman kami ng puson ko mabigat n naman. I went home early and sa bed itinaas ko s wall ung legs ko. Nawala naman kahit pano ung bigat s puson ko. But I cant even walk straight para akong kuba lumakad papunta s cr. Is this normal? Tapos oa lang po ako magisip? Kc takot ako. I dont want to lose a child. Ftm here and 18weeks preggy. Please suggest or any thoughts? I will really appreciate mommies! ❤
