I had implantation bleeding the same day as my expected period which was July 15th, it was very light , more of just spotting I would say lasted about 4 days by the 5th day it was there only when I wiped that morning very light pink ! I have taken 4 hpt , they've been negative so far . Is it because I may not be far enough ? I have an u/s app tomorrow at planned parenthood will they be able to see anything or atleast tell me my hcg levels ?? I am so nervous . What should I expect ? Help !!!??
