Alamak, 36 weeks sudah mau habis kan, sakit celah paha tu memang common masa akhir pregnancy, entah ligament stretching or baby positioning, tapi sebab ni area yang agak sensitive better check dengan doctor saja to be safe, especially kalau sakit tu persistent or tak improve. A few of my mum friends ada yang complain the same thing dekat third trimester, and doktor diorang kata it's normal but still kena monitor. Jangan worry banyak sangat lah, you're almost there!
