I’m at my wits end.

I’m over a month late for my period. I’ve gotten negative tests, except I’ve NEVER been this late. These last couple months have been relatively stress free, I’m not dieting, I’m not on medications, nada. Today I looked up what pregnancy is like at 10 weeks (which is where I’d be) and I literally am experiencing ALL of the symptoms, some of which aren’t normal PMS symptoms for me (like migraines, extreme bloating/gas, and constipation). My doctor is not concerned (I don’t have access to very good healthcare in my area). Is it possible I am pregnant? Has anyone else been in this boat? I’m so confused.
