19 days late, negative pregnancy tests - how common is this - women to have low HCG?

Hello
I have missed my period of 5/17/16 and we are already in June 5 2016 I took a pregnancy test but it wasnt early morning pee.. It came out Negative .. I have soarness on my boobies and also back lower pains and sometime get a bit a cramps. I want to know if their is any possibilities or should i go to the doctor or if i took the preganacy test too early or wrong.. This would be the first time i do anything like this.

Hi I don't know if anyone can help or offer any advice, my period is 17 days late my last period was 2/2/16 then I missed one due on the 1/3/16 I have took 4 hpt and they have all been negative, I'm due another period on 22/3/16 and I really don't know if it will come, I have been going to the loo a little more often, I don't have sore/tender breasts but I have been feeling a bit sick, I also have a mild cramping in my stomach like cramp but not as sore just doesn't feel rite, we are trying for a baby so every negative test is more stress !!, iv never missed a period before so my hopes are high I'm so anxious !!!! I phoned my doctor and he said try next week !! Anyone who can help please !!! Thanks xxx

Hey ladies, I have had 3 beautiful girls, each one has taken different times to read a hcg level. My first I did not get a positive urine test until I was 8 weeks along, my second child I did not get a positive until I was 11 weeks along. And my third I was 4 weeks. Doctors kept telling me I was not pregnant and I would believe them. Each time I would take a positive test into show my doctor he would say oh you must have ovulated late but my ultrasound would prove them wrong.
Hope this helps anyone who feels lost in these times waiting to either get your period or that positive result

I can say that I am in the same boat. I am 19 days late on my period. My last period was December 27th. I've tried several test and all came out negative including the blood test at my doctor. He wants to start me on some meds to make my period come on but I dont want to do that. So, I'm kind of stuck because I don't know what to do. I do have some symptoms of pregnancy but not all. I also have a dou le uterus. Thats another reason im stuck and afraid.
