AF late🤔🤔 freaking out!!

4 months PP. after my post delivery bleed I had a 13 day AF May 28th-June 9th which was kind of heavy. Had my next AF July 12th - 16th which was light; 1 pad a day light. Now I’m 2 days late. I was on the pill however since the 16th of July chose To do a FAM; tracking my CM. The only time my CM has been within the range of ovulation was June 27th-29th which was watery. Was dry then had egg white CM July 1st - 3rd. Wondering if July’s light AF was implantation.

I tested last week due to; increased appetite (HUNGRY ALL THE TIME!!), nausea, severe exhaustion and the tests were all faint to some looking negative and all 3 betas were negative. But now that I’m late, what are the odds of me being pregnant or this just being my body getting back to normal and missing an AF?

No withdrawal or condom on June 28th, during 2nd pill pack. CM since July 16th has stayed a consistent creamy CM.

Advice? Thoughts? Woman to woman honesty please.

First baby.
