Brief Answer:
Pregnancy ????

Detailed Answer:
Hello XXXX
Your last menses date was 12th XXXXXXX .
Unprotected sex on 29th XXXXXXX .
Ovulation should be around on 14th-15th day after 12th XXXXXXX i.e. 26th 27th XXXXXXX and sex on 29th XXXXXXX . Ovum usually remain active for 48 hours so in your case there is no chance of pregnancy ( 99 % NO CHANCE). All these calculations are based for regular period of 28 days( 5 days flow).
You did home pregnancy test on 19th and 20th July , also negative .
In my opinion heavy flow for one day was normal but due to tension .
No chance of pregnancy.
-Safe day sex
-pregnancy test negative
-heavy flow ( bleeding).
So no pregnancy.
Good luck.
