Thrush!! Help I'm confused

B
So I had thrush a few days ago and got a canesten... All sorted lovely job... The night after I had sex. And there was pink discharge coming away. And I've had it ever since and it's quite thick... Do I need another canesten, doctors or?? Really could do with some help if anyone has had the same. I've had thrush before but never this colour and thickness. There's no possible way of an STI as we use condoms so help would be appreciated!
