Hi im 27 yrs old and my last day of my period was april 19 i took 7 home pregnancies test and they showed negative. I called my obgyn and told them my situation my dr wanted me to do urine and blood test this was all done on monday may 23 2011 got my results the next day which was negative urine test but a positive blood test. On wendnesday i started to feel cramping my breast have been feeling sore and lower back pain. On saturday i decided to go to the er because of my cramping and lower back pain. I just wanted to know if everything was ok with my pregnancy. At the er they did a urine test and a hcg blood level test and the urine came back negatative and blood test came back as 0.5 hcg level meaning negative. I was devasted to find out this information. So my question is could i still be pregnant even though my hcg level is 0.5 but have had a positive blood test on monday? Could that mean that im still very early maybe just days? Please help me im very confused.
