I badly needed your help! Here's my situation.. I'm almost 1 month and 13 days delayed. My aunt flow is always regular.. and I don't have any issues of hormonal imbalance or amenorrhea. And I know, I'm pregnant because I'm experiencing some pregnancy symptoms. Well, I already consulted a doctor and she just said that I'm under observation. My problem is my hcg cannot be detected by hpt, and I also did a blood test but still negative. Is there some cases that a women is pregnant but her hcg cannot be detected or maybe low? Well! I have read some articles about it. Help!
