okay so about a week ago (lol I had to)

but anyways about a week ago I took 2 pregnancy tests & they both came out positive...... but the thing is my mother is very religious & she didn’t want me having sex with my boyfriend until marriage.... & a couple days ago she asked me if we were having sex & I told her no.....

I have no idea what I am supposed to do or even when to tell her that i’m ‘pregnant’ should I wait a couple months until I start to show??? or should I tell her soon ????
