Advice please

Hey a little helpful advice please.

I have 3 beautiful and healthy babies(15yr,14yr, 2yrn 2 boys and a girl). We recently lost baby #4 (a girl) in April. Now everywhere that I look everyone is pregnant. I dont want to replace the one we lost but I also dont want my 2yr growing up being "only child".

O and I'm about 2 days late. Took a test this morning and nothing. Anything at all ladies
