Trying to get pregnant

Im 37 years old will be 38 in few months time and me and my partner have just started trying fora nother baby,i have 5 children i total 4 boys 1 girl the girl being my youngest.i guess i just little worried what people think as i see people's face when they see me with my kids.i know some of my family was not happy when i had my last baby and said some horrible things to me and my children and didnt speak for months.i guess i also worried what they might think and say,i know i shouldnt really care what they think or say but it just plays on my mind that it will be like last time and i dont want the stress as i suffer with anxiety
