Rising hcg but not doubling (good news)

Ok so I found out july 14th that I was pregnant I was so excited I went strait to the doctor and got a blood test my 1st hcg level was 130 and my progesterone was 39 I believe wich was great but my second blood test only went up to 205 doctor said it wasn't rising as it should and I need another blood test so a few days later I got one and the levels was 322 the doc said prepare my self for a miscarriage I was so crushed I googled and there was happy story's and sad ones also the main thing is I tried not to stress.  A few days later I  got another test done and the results came back at 2474!!!!! The doctor said that I'm right on track now !!!! So relived and excited I go for ultrasound in 2 weeks Praying this baby is growing  good thank you God   For my little miracle baby on the way  I'm posting this for everyone who was in my case to show you to never loose hope sometimes the doctors can be wrong PrayhopeAndDontWorry
