Ai mama, senggugut dan cirit-birit tu memang normal dalam early pregnancy sebab hormone changes, tapi since you're only 4 weeks, definitely worth checking with your doctor just to confirm semuanya okay dan exclude any issues, better safe than sorry, especially with the cramping. A few of my mum friends experienced exactly this early on and their doctors gave them peace of mind, so go ahead and book that appointment, okay? The nipple tenderness is very typical pregnancy sign but the doctor will want to assess the cramping just to be sure. Lepas jumpa doctor kita boleh chat pasal apa-apa lagi you're worried about!
