How long does the pill take?

I had been on the pill for over a year but decided to take a break since it was affecting my mental health quite badly, i took a break for over 6 months and have been prescribed another brand.

I have been taking this one for about 2 weeks now and was wondering how long it takes to take effect on my body?

It hasn’t been too long but i’ve already noticed a big change in my mood and my sex drive seems to have decreased by a lot, i don’t feel as turned on or interested in doing anything as much…

could that be due to the pill, is it too soon to tell or is it just my body being weird?
