35, 5'7, 242, and I am 70 days late for my cycle. I went to the doctor she ran some test and told me to come back in a month. She did tell me that I had a lot of mucus in my vagina and cervix. Yesterday I went to the restroom and there was light brown discharge. I am scared because, I have taken 2 home pregnancy test and they came back negative. I took the test about a month in a half ago.
