I Was Having Pregnancy Symptoms So I Took Several Tests,

I was having pregnancy symptoms so I took several tests, two of which came back positive. Roughly three days after my period was expected I got heavy bleeding that was unlike my normal period and only lasted, off and on, for about two and a half days. About a day after that I started seeing brownish, pink colored discharge when I wiped after going to the restroom. I'm still having what seem like pregnancy symptoms and the spotting lasted for about three days off and on as well. I am very unsure of what is going on and I was hoping someone could help me.. I was and am experiencing bloating, nausea with vomiting, fatigue, food cravings and aversions, back and shoulder pain, mild abdominal cramping, headaches accompanied with dizziness, breast tenderness and enlargement, restlessness, and colored vaginal discharge.
