Ashamed ? But not?

How to deal with this,

I had a miscarriage two years ago, took me 2 years to grieve my loss.

I had a child before my loss.

When I was pregnant with him I was 19-20 years old, everybody made me feel like I should not be happy and pretty much was a mistake. My mother hid my pregnancy, my siblings stop talking to me, I had no friends, I finished college, I moved out, me and my partner own out place now, never had any help with anybody at all. I don’t get breaks ever I am I stay at home mom and love my son.

I am pregnant again and haven’t told anybody about my pregnancy, I am 17 weeks. My family suspects but don’t know already decided to stop distance them selfs again.

I am still young 23. I feel like I should be not happy even though I prayed for this. I am so happy. Nobody knows about my loss I am afraid it will happen again.

I need advice. Please should I be ashamed ? How can I be strong enough to stand up for myself. I haven’t shared the very exciting news because I don’t want to deal with everybody es unnecessary negativity!
