Cramp perut

Eh, cramp at 5 weeks is quite normal lah, tapi memang better safe than sorry especially first baby, I'd suggest you call your doctor or clinic and ask if you should come in sooner rather than tunggu scheduled appointment, just untuk peace of mind kan. Most docs prefer to see you around 8-12 weeks for first scan, tapi if you're cramping and worried, they won't mind checking you earlier, a few of my mum friends did that with their first pregnancy and rasa better after seeing the heartbeat. Keep an eye on bleeding or intense pain la, if ada tu, go straight to clinic/hospital yes, jangan tunggu. Congrats on your first baby!
