Hi all. Currently at 7 weeks 5 days, felt dizzy all night. Had some brown spotting earlier and now a string of pinkish blood. I am getting the same feeling as during my period with my legs feeling achy. My pregnancy symptoms disappeared and i had very bad nausea for 1st and 2nd pregnancy, as well as this one. Any advice? The earliest i can do blood tests is tomorrow. When i did one yesterday, my bhcG had jumped from 8,6K two days prior to 18K. I am seeing my doctor anyway on Monday.
