Rant about family

So I got sick late last night and I have been throwing up since I finally was able to eat some food without getting sick ....my family keeps saying "you're pregnant" "the first trimester isn't that bad" and it's starting to piss me off ....I am on the Nexplanon Implant and yes me and my boyfriend does have sex and he finishes in me but I haven't had a period since getting my implant ...I'm gonna go buy a test just to clear my head even though I know I'm not pregnant .....why are some family members just so rude!!!!
