Did yo uend up pregnant even though your test was negative?

I am 8 months PP with my daughter. I am on BC & we use condoms as well. In august I had some symptoms of pregnancy, however I tested and it was negative so I left it alone. Fast forward to last week I started feeling flutters like I did when I first felt my daughter move. It comes and goes. Isn’t constant. It’s not gas. The only time I have ever felt this feeling was when I was pregnant, except for now. I took 2 home tests and both negative. I contacted my doctor and she said it’s rare to have a negative home test and actually be pregnant. So I took another test and it’s negative. Am I crazy?! Have any of you had a negative home test and ended up actually being pregnant?I asked to have an HCG level drawn and my doctor wasn’t a fan of the idea.
