Late period

G

So my last period was March 24th-March 30th and I haven’t had one since it’s now 31st May, but I haven’t had sex since my last period, the last time I had sex was 14th March. I stopped taking cerazette however at the start of April. Am I pregnant or is stopping cerazette caused this? I squeezed my nipple today and white liquid (not much at all and it was watery) came out so now I am stressed, I haven’t gained any weight though.
