Am I pregnant or paranoid?

I lost my virginity a week ago, 3 days before I was supposed to come on my period.

On the day my period was due I got the contraceptive implant which stops 1 in 5 women’s periods altogether.

It’s been 5 days since my period was supposed to come on and it still hasn’t. I’ve been getting white discharge a lot lately as well.

I’ve spoken to my mum about worrying whether I’m pregnant and she says that she thinks the implant has stopped my period, I however am still worried.

Yes I did have sex, I used protection and it was after my fertile window so I don’t know whether I’m just being paranoid.

I would really love some help and advice right about now.
