Opinions!? Help please!!

I have been TTC for a few months now and last month (june) i had dark spots on my boobs.. My best friend researched and said it was early signs of pregnancy, i took two tests that day and they were negative. Well later on that week i had brown discharge For a day and a half so i took a pregnancy test two days later and it was positive.  Within three hours i had severe cramping and violently bleeding for about 3 days. I need help!
