can feel your loss for your baby, which is natural as it was part of you for 8 weeks. But having supportive husband & friends is a blessing. it is ok to cry for your loss, nothing wrong to hold this special memory & bonding. but if you plan to have a baby again, not sure if you have a religion, think of the baby going to a better place.
Do not blame yourself. I believe that you had done your best in trying to provide the best enviroment for baby to grow in. however sometimes such things happen, maybe for a reason, which i also dont really understand. Look at the beauty of still being alive, still having the chance of conceving again. Yes , it would b beneficial to take some nutrition/ supplement if the constitution of our body is not strong enough. I can share more about such things if you want. But that is not impt as at now.
Take some time, do things that you enjoy. eg read a book, go for a moive, meet girlfriends for high tea / coffee. or even go for a date with your hubby.
In life , it 's impt to be able to pick ourselves up when things goes wrong, coz after storm, there's always a rainbow & the storm will not last forever.
