Chemical pregnancy??

anon

I found out the day my period was supposed to come that I was pregnant. Well, due to very light spotting I went in to see my doctor and when I took a test at the clinic, ( only hours away from my first test) the doctor said the positive line was very light indicating it may be a chemical pregnancy. That was 2 days ago and I haven’t been having any cramps or bleeding and now I’m getting pregnancy symptoms such as fatigue and constantly wanting to eat. Has anyone experienced this? How long would it take to get my ‘period’ if it was a chemical? And would I be feeling pregnancy symptoms if it was a chemical pregnancy? TIA!
