Oo normal yan sa 34 weeks, mama, ang baby ay umabot na ng decent size kaya ang back pain at tiyan discomfort ay expected, plus ang sleep ay talagang mahirap dahil sa position at kicks! But since ang pain mo ay consistent na, better check with your OB para ma-assess kung normal lang pregnancy aches or may kailangan i-address, especially since kailangan mo ng proper rest before labor. A few of my mum friends had the same issue at naloko kami kung anong normal versus concerning, so ang doctor lang talaga ang makakapagsabi ng sure. Take care, mama, almost there na!
