Should I tell or wait

Marquita

I recently gave birth to my first child via cesarean 1/10/19, well i had my first cycle in February well I went for my 8wk checkup & I was suppose to start my BC the Sunday after my period went off well needless to say I never got my cycle. Went back to Dr on 4/1/19 & tested positive. So far no one in my husband or my family knows. Should we tell or just wait?? This will be both our 2nd child but it’s so soon
