False Negatives??

I'm going to break this down as short as possible so it's not too too long.

I'll start at the end of June when I received my period.

I started my period June 29th and ended July 4th.

I restarted my period July 31st and ended August 5th.

I ovulated August 19th and had sex that day as well.

**My periods are very regular**

I was suppose to start again on September 2nd, I missed it nothing came, pregnancy test was NEGATIVE.

Took another pregnancy test September 6th, NEGATIVE. And again on September 11th, also NEGATIVE.

I am 11 days late, on cycle day #45 which is waaaayyy to long for me.

I've gotten cramps here and there since I've missed my period and a little before that but no period and no spotting. I really feel like I'm pregnant but I'm testing negative since I've missed my period. (also can't get a blood test from my Dr because I have to be minimum 3 months without a period, strange)

If anyone experienced anything like this plz plz let me know your story and the outcome. Hoping baby #2 is in there.

** Side note, my period is not delayed from stress lol, there's no stress**
