Awww sayang, I can feel the disappointment through your message Delayed period with negative UPT can happen due to stress, hormonal changes, weight fluctuations, or even just the body being moody, a few of my mum friends went through this before and it turned out fine jugak. Since you're 11 days late though, I'd suggest pop by the clinic just to check everything's okay and get some peace of mind, boleh? Sometimes the doctor can do a blood test if needed, and at least you'll know what's going on with your cycle. Hang in there, things usually settle down soon
