Wa'alaikumassalam sis! 5 weeks dah, so line should be terang by now, kadang-kadang sensitivity UPT berbeza or maybe timing of test je, tapi samar gitu agak concerning so better check with your doctor asap dapat confirm and peace of mind dapat la! A few of my mum friends yang experience samar line memang suruh repeat test or go straight to clinic je, sebab sometimes hormone levels still building up or UPT yang kurang sensitive. Congrats on your first baby journey though!
