hi. please continue to monitor your symptoms po. you could be entering the early stages of labor and at 34weeks, hindi pa dapat. but ofcourse, preterm labors can happen. i strongly advise to alert your OB kung may nararamdaman ka na hindi normal para sa'yo. "naninigas ang tiyan"-- as long as hindi masakit at hindi consistent ang timing, it could just be braxton hicks contraction. you can try to just change position and it should fade. "masakit na balakang pag palage naka upo" -- normal lang yan, best if you do light exercises like walking. at this stage, iwasan naten matagal naka upo or nakatayo because it causes sore muscles nga like what you are feeling. if still worried, talk to your OB :)
34 weeks ka palang momsh? Ako EDD ko April 9 pero 36weeks and 3days nako ngayon
