Sounds like my boss (although I am not a young Mum & it's our 3rd), but she asked why were we not using protection?
Thankfully I was on the phone to her at the time coz I wanted to laugh, cry & p[unch her!
My 1st was not planned, but is the light of my life (well all my kids are/ will be) But maddy & I have a very close super bond....

I dont carew hat5 anyone else thinks of me, I am very happy & confident with my choices, decisions & hapyy with who I am as a person...

You should hold your head high & say I am proud to be carrying my DP's baby, I lopve him, he loves me & we are having a baby! Planned, unplanned is not the concern... What you say now your friends (or so called at the mere fact they are asking those questions?) will throw your comments back in your faces later on, if you ever say OHHH I wish the baby would: sleep, burp, not ppp so muchj, smile, talk, laugh, etc etc... They'll say crap like...
"Well I guess it was a mistake so what doi you expect etc, etc!"

Dont give their opinions a second thought... Your obviously happy about being preg & so is DP, so enjoy that & each other... anyone else is an outsider in your relationship & life choices! Dont let them amke you feel bad, down or guilty..... Often its' their own jealousy!!

Best of luck for a positive pregnancy experience & a gorgeous much loved healthy bubba in the future!!!
