Pregnancy Symptoms - negative test results!

[Hi. I am going through the same thing, Its so fustrating. For the last two months everything has gone wierd..Ive had missed periods . only light bleeding that lasts a day and a half.. (I have always been regular) and lower backache that hit me out of the blue and lasted only one day. ( someone told me this could be a result of my joints and ligaments loosening) It progressivly got worse during the day till I could barely walk then dulled later that night, and then I was fine the next day! Even wierder I have noticed the change in the shape of my bellybutton!. It is an innie and used to be deep .. now it has become shallow and pinched in. At the moment it resembles some wierd eye!

I have taken some pregancy tests but they have been negative and I have no symptoms. I have been to the doctors, but they have dismissive and wont tell me more... I am hoping an answer will come soon and like you.. what will be will be..

I had unprotected sex around the time of ovulation, and this past week iv been having odd symptoms my tummy is really swollen and i have had sickness in the evening and my breasts are sore and tender. Im not exactly sure when i am due on my period i think its in four days. (i do really need to keep track of my cycle but its so irregular i tend to just go with the flow!) Today i took a clear blue pregnancy test and it showed up negative. I was really gutted by this as me and my partner are trying for a baby. Even though it saying i am not pregnant i genuinely feel *pregnant* if that makes any seance. I really dont know what to do? Should i wait a few weeks and if no period then take another?

I have basically the same question!! About 2 weeks ago I started to experience the following symptoms: constant nausea, severe lower back pain (something I've never had before), strange cramping in lower abdomen, hunger/cravings, diarrhea, dizziness, extreme bloat (I LOOK pregnant) and intense mood swings/irritability. Since then the nausea has become milder, diarrhea has become constipation, nipples are slightly sore to touch, my skin has broken out (unusual for me), frequent urination (i get up in the middle of the night to pee, then realize i'm starving and raid the fridge LOL) , I have unusual sleep patterns, strange dreams and I've had major heartburn for the past couple of days.

I was basically convinced I was pregnant, even though the symptoms started very soon after I had just had my period AND that i had just recently stopped taking the birth control pill. SO i started taking hpts every couple of days. They were negative except for one clear blue test that showed the positive "+" but the control window was empty therefore I deemed it faulty. I went to my doctor a few days ago to take a blood sample and the next morning he left a message on my phone saying "you are NOT pregnant".
Not only was i disappointed with the results, but not entirely convinced either. I've been trying to continue on with things without letting it cloud my life too much, but cannot seem to get it off my mind.
I read over and over again about women who have tested negative for weeks, though find out later they are and always were in fact pregnant.
So I'm wondering what my chances are... how common is it really to have negative blood and urine tests and end up being pregnant?
PLEASE post your thoughts, I need some advice and success stories!!!
OHH and by the way, I am not expecting my period for another 4 or 5 days so I realize it is still quite early to know.
