Hey there. Welcome to BB.

I have a higher BMI than you and gave had 3 pregnancies I have gained alittle over 3kgs for this pregnancy and feel great.

Being overweight on it's own isn't a reason to not fall pg easily- it's the other stuff that happens as a result of being overweight that does it such as hormone imbalances causing irregular periods etc.

Best of luck luv and I look forward to seeing your pregnancy announcement sometime soon I hope
