Sayang, cramping dan hardness in the womb area during early pregnancy can happen, but sebab ni sensitive period, better you check with your doctor or gynae asap ya, even if it comes and goes, okay to get peace of mind! A few of my mum friends experienced similar things at 7 weeks, but setiap pregnancy lain-lain so jangan main-main. Early pregnancy ni banyak changes happening, tapi doctor je yang boleh confirm semua okay. Don't wait lah, call your clinic and get checked properly!
