Red marks on my inner lips of the vag

3 days ago I used some knickers, it made my vagina itch so much. So I threw them away. But since then its been itching all the time and now my lips have swollen.

I've been looking around down there and I can see red dots in the inner lip of the vagina.

In don't know if this is because of the knickers I've used or the fact that I've been taking my first pack of hormonal contraceptives.

I've read in the internet that it can alter your hormonal balance and therefore cause candidiasis.

Any suggestions as to what I can do apart from seeking medical advice? ( I'm gonna go to the gynecologist soon)

Any past/current experiences? What did you ladies do?

P.S. I don't think this was caused from having sexual relationships with my partner.
