should i feel this way?

this is just a very upsetting topic for me, it always upsets me when i see people celebrating being/ getting pregnant as i can’t. ive had two miscarriage and have tried for months to get pregnant with no luck, i feel selfish bc these girls getting pregnant can barely afford the clothes on their backs and don’t even have a place they can really call home, but they can still get pregnant. i know i would be a great mother but this drags me down so low 😞 i just want a baby and i see everyone else getting pregnant it just makes me depressed.. everyone tells me i have plenty of time to have a child but i can’t get pregnant and people don’t seem to understand ☹️
