Sorry for the long post before hand. In January 2015 I had a ectopic pregnancy and lost my left Fallopian tube because it ruptured. Then in June I got pregnant again and it ended in a miscarriage before it happen I had to get blood work done because of the ectopic and it was very stressful well now I am pregnant again and I suppose to go to the doctor right away for blood work but I am afraid that it is just to stressful again but I can't really ignore the doctor for so long. I don't really know what what to do. I know it is better to get it done.
