I went off birth control for a month because my doctor told me to

I went off a month on my birth control because my doctor told me to, I knew when I ovulated because it was confirmed by a doctor. I told my fiancé but he still wanted to have sex(even though he doesn't want another kid right now) we have a baby. And now I think I might be pregnant, it's a day before my period is supposed come. So I put my patch back on, should I not have done that? I'm super bloated my tummy's all hard in weird places. I never had that as a side effect. Can someone please help? I took a pregnancy test 3 days ago and it was negative. Should I take another one?
