Cramping, Rasa sakit setiap kali buang air besar

Saya baru 6w3d belum pernah check up or anything, tapi kerap cramp mcm senggugut, sakit kepala, setiap kali buang air besar rasa sakit sangat perut. Ambil masa stgh jam utk okay. Pernah sekali cirit birit, after that saya pengsan. Is it that dangerous? And one more, saya kerap naik motor since that's the only choice I have.
