Needing much help please !!

Day 9 I felt a pinch on my left ovary thought it was implantation. Day 13 I got my positive day 14 I cramped and bled all day (my period wasnt supposed to start till 2 days later and my periods are always on point) day 15 I bled for a few hours. Day 15 later on it stopped completely . Day 16 im nauseas(hurled once), have diarrhea, frequent urination and am spotting but with absolutely no cramps at all . Any idea what the heck this means
