Can anyone shed a bit of light...please :(

hi all,

I posted a couple of times following problems with positive then negative pregnancy tests. When all came to all my go said it was likely I had a chemical pregnancy. What's going on now im still totally confused by. Let me break it down into dates.

my last period was the 26th may

my positive pregnancy test was 7th july

Negative test was 8th july

on the 12th July I had a super positive OPKso got down to business.

its now the 26th July, no bleed, no positive test. 

I really dont don't know what my body is doing. My gp is not interested in the slightest. Only if I become unwell, have a catastrophic bleed or develop severe pain. Im completely lost.
