Pregnancy levels


So I got a positive pregnancy test on Thursday. I also had a appointment with my doctor yesterday. So I took a pregnancy test at the dr and still positive. We did a blood test and got the results today. Dr said that my levels are very low only about 14 when they usually should read about 50. My period is still not due for another five days. Is this normal Will my levels increase in the next couple days ? I got my fingers crossed for good news

Update: levels are now over 100 and hoping to see little babe on an ultrasound soon
