Hello Welcome to HCM, thanks for posting your query.
1st thing 1st, with this scenario there is no chance of
pregnancy. So do not worry.
I read your question and understood the situation.
With such a small quantity touching clittoris, there is minimal or no chance of pregnancy at all.
So I suggest you to not worry and be happy.
In this regard, I suggest you to be chilled out and make no worries for self and also to the girl.
The symptoms that you said,
vomiting and all could by itself be a different problem.
White discharge indicates,
pelvic inflammatory disease which is a kind of infection. Usually, that will be observed if it's not troubling the patient much.
Hence I request you to stop worrying and be happy, that's the most important thing to do.
In case you need any further assistance, feel free to contact me.
Take care.
