hi jaffa,
first of all congrats, i wish you good luck and hope this movement will certainly bring u a positive news soon,
i am in ur same situation, i did mention a self employed work in personal history for a certain period, i explained that i was doing that as an extra job to make some extra money, but i didn't mentioned that in work history otherwise i had to upload all requested documents like pay stubs etc, but as specified self employed i had about nothing related to that, pls keep updated, hope they will not ask me something.
btw i applied in 16 may- fst, no movements still, but its ok, we have 6 mnths.
