These are test that I took on September 29 & September 30 they are faint but look positive to me. My lmp was September 5th. I am suppose to start today according to my glow. But I have been feeling cramp for the last three days off and on cramps. So on Thursday I went to the dr to get a blood test done and my hcg level say <5 why is that? And how can that be because I see that I have 5 positive faint line test. And when would my hcg levels go up? What was everyone hcg levels at 3 weeks or so according to my last period I should be 3weeks??
