Emotional

So i had my first miscarriage last month and i was crushed . Just couldn't believe it ,like it was a dream I couldn't wake up from.Had a lil light bleeding no cramps, went to the er and was told there was no hb.after more doctors appointment it was confirmed and had a d&c. I honestly dont know how to feel i didnt feel like i gave myself a lot of time to grieve, just accepted what happened and tried to be positive. But lately my emotions are all over .im ok and then sad , and seeing a ton of pregnant women everywhere makes me sad and miss my baby.. i dont know what to do .I know i need to stay positive :(
