Sayang, at 33 weeks pain like this kena check dengan doctor sekarang juga , jangan tunggu. Pinggang sakit + perut sakit skejap-skejap bisa jadi banyak benda, dari Braxton Hicks, ligament pain, ke something yang perlu perhatian medical. Better safe than sorry, especially this close to labour. Ring your clinic or go to the hospital if the pain is getting worse or if you feel anything unusual. Let me know okay, sending you strength!
