Pregnancy chances after negative blood test?

It's 7 weeks exactly after the first day of my last menstruation. I done 2 home pregnancy tests, on the first day of expected menstruation and one 3 days later, both faint lines but positive. Besides that I have experienced heavy pregnancy symptoms: Nausea (some days bad, others none, vomiting once only); Extreme fatigue since 1 week after ovulation til current; Hunger; Frequent urination since 2 weeks after ovulation; Back ache, Dizziness (especially when standing long); Food aversions & cravings; Enlarged breasts (gone up about a cup size in 3 weeks); Sore & heavy breast since ovulation; Small bumps on areolas; Frequent headaches. All went well til blood test was done on Saturday which turned out negative??? I don't understand this? Shouldn't the blood test pick up even if my levels are low? It should be quite high around 7 weeks? I'm soo confused. The doc didn't even do an u/s or medical examination or anything? What can cause breast enlargement? Please help, I'm going crazy!!!

Try and do another blood test and request an ultra sound. Good luck

False negative results are more common than false positive. What type of test were you using? If it was a test with blue dye test I would go out and get a different test like the First Response, they use pink dye, and are less likely to have an evaporation line (false positive), or but a digital.

Thank you so much for your reply and the advice. I have used 2 different brands but both with pink dye and I made sure that I checked the response within the time limit. The second line appeared within seconds both times. I have done many many tests before and this is the first time since I had my m/c about 5 years ago that even a faint line appeared. And I haven't had evap lines on them before that's why I don't understand this? I just think the doc should have at least done an u/s to make sure everything is still allright and that it was just a weird fluke or something...

Your right if indeed you were 7 weeks gone even a HPT would be accurate,a blood test is the most accurate test you could have it would show positive by now.it detects very low levels of Hcg,your doctor obviously hasnt done a scan,as they think your not pregnant due to blood test results.its possible you dont ovulate properly,this will prevent you from having a period.you need to ask your doctor for other tests in order to work out why your not having your periods.try a digital.
