help please

So last ago I got extremely faint line positives, for 4 days straight, I was feeling sick, sore boobs and bad cramps. I then got negatives ever since. I am now 2 weeks late for my period and still getting some symptoms but no where near as much as I was getting before or anywhere near as bad.

I went to the doctors and she said it wouldn’t have been a chemical pregnancy as I would be bleeding by now.

I’m so worried and wondered if anyone else has experienced this before?
