Blood Drug Testing

How accurate is a blood pregnancy test taken at the hospital?

I've been struggling with whether I am pregnant or not for over a month now. My boyfriend and i had protected sex between the 10th and 25th of January multiple times. In the beggining of Febuary I started feeeling odd sensations in my stomach and immediatly bought a home pregnancy test which came out with a ngeative result. I waited for my period to come in January but it did not, which didn't come as a suprise as my period has NEVER been regular.I tested all through the month of Febuary using first morning urine, differnat times throughout the day, everything (these things are not cheap!)and all coming out with negative results. About a week and a half ago though, I was using an E.P.T. pregnancy test with blue dye, the plus/minus kind, and th initial result was negative, but after leaving the house and coming back a very very thin choppy blue vertical line had appeared. I read the instructions and it said not to let it sit for more than 10 minuets, after that the results would be invalid. The next day i tested again, this time using 2 digital test. both came out "not pregnant". I went to a planned parenthood clinic thinking that i could possibly be testing myself wrong, and the nurse came back, clear negative result. This is stressing me out beyond belief i want to know what is going on with my body ASAP. After going to the clinic i was still skeptical, so i scheduled to have a blood test done at the hospital yesterday, March 1. Even though i was almost positive that if i was this far a long it would have shown clearly on a urine test. I called this morning and the nurse told me the blood test was negative. How accurate is this test? I'm still worried about this. My mom thinks im worrying myself crazy, but this is important information that i ned to know as soon as possible, as this could affect my life forever. How large of a chance is there that the blood test at the hospital could be incorrect? The pregnancy test that came up with a very think vertical line after it sit for a while is completely thowing me off.

1. They are pretty accurate but not 100%. You still have a chance. My moms friend tested with hpt's and even got 2 blood test done and they all came up negative. Finally she had them do an ultrasound because her period didnt show up for 3 months and long and behold she was 3 months pregnant. Its rare but it can happen.
2. You are not pregnant. Relax. Those tests are as close to 100% as you can be. It sounds like you think you are pregnant because of some odd sensations in your stomach a month ago. In my experience (I'm currently on my 4th pregnancy!) you don't feel anything in your stomach that early. It was probably gas/hunger
3. Blood pregnancy tests are extremely accurate, particularly when combined with the results of 15 different home tests. How much more information do you need to see before you accept that you are not pregnant? If you have irregular periods, this should be run-of-the-mill for you.......
4. You're not pregnant. You said that your period is never regular. That, coupled with all this stress you're placing on yourself, makes it even less regular. Also, you wouldn't feel anything in your stomach already. The blood test is almost 100% accurate, as are HPT used correctly. You'd be far enough along to test accurately. So relax. ;)
5. blood tests are very accurate, you've taken a crap load of HPT's and they all said negative. Maybe your periods aren't coming because you're stressing yourself out so much over nothing. Just relax, you're obviously not pregnant.
