So little history first Iv had 2 miscarriages in the past and have had an ovarian cyst rupture in which they had to removed my right ovary. My left ovary I still have but have had surgery on for a cyst removal. I have not been diagnosed with any medical issues regardless any of this.

So I havnt been being safe to protect aganst pregnancy so it already had it in my mind I could get pregnant and I felt pregnant before I even missed my period ( 5 days before my predicted period) so that morning I tested anyways knowing it could be to soon but I got two positive test

So the next day ( 4 days before my predicted period) I went to test again and now the tests are a lot fainter and more so look negative to me. So I took 3 tests this time. All day Iv felt  nauseous and have had a horrible migraine. Is this most likely a chemical pregnancy?
