Aww sayang, abdominal pain at 5 weeks kena check with your doctor or gynae ASAP lah, jangan delay. Cramping, dizziness, and pain moving around like that memang perlu proper assessment. I know it's scary, tapi tak boleh guess-guess at this stage. Call your clinic today or if it gets worse or you see any spotting, go to A&E straightaway okay? Better safe than sorry lah. Sending you hugs, get checked out soon!
