What are you thoughts?

I’m beyond confused and frustrated. I’m 12 days late for my period. I thought I had positives two weeks after sex, but maybe they were indents or a chemical. This possible pregnancy would be from September 23rd. It’s now October 21st (well in less than a hour) and still no period 12 days late. That’s not normal for me. I’m getting negative tests. I went to the ER at 9 days late for pain and wondering if it was ectopic. Hcg blood test was negative and nothing seen on ultrasound. But, they said it could be too early to see anything. But, I should have blazing positives by now and at least see a sac. I have symptoms here and there and just don’t feel myself.

I’ve been reading all these glow posts about super late BFP and/or never testing positive and seeing the baby weeks later than normal on the screen. I keep getting hope for something I don’t think is there🥺. What are your thoughts?
