Hay sis, I'm so sorry you're going through this, two miscarriages and now finding out you're pregnant while separated is really heavy A few of us mums went through something similar, and honestly ang dami ng emotions na nagsasama-sama, walang excitement because of the stress and hurt, so totally normal yan. For now focus mo muna sarili mo, the baby, at ang peace of mind mo, kailangan mong magpageck up sa OB soon para siguruhing okay ang pregnancy especially after two losses, and para ma-settle din ang mind mo a bit. Whatever you decide about telling him or not, that's your call, but please make sure you have support around you, kahit friends or family lang, kasi ang journey na ito ay kailangan mo ng peace, hindi stress.
