Please help me out, so worried!!!😭

Okay moms, and moms to be. I took a pregnancy test because I noticed my LH test strips were very dark, it came back positive but my period ended a week ago, can anyone tell me if they’ve experienced this. I’ve reached out to a few of my mom friends and they’ve told me that some women do get their last period and are pregnant, my ob said that I could actually be pregnant from the month of July.. I am a mess. Crying, and freaking out because this is all I’ve dreamed of, my ob wouldn’t get me in till September 9th so please ladies if you’ve ever experienced it let me know, ALSO I’m getting yellow/ brown discharge now when I wipe so please let me know
