My 12th july baby came on 18th June

My 12th july baby came in 18th June, weighs 1.8 kg, her weight did not increased inside after 31-32 weeks, placenta they took out was very thin. It was a natural labour, but I bleed a night before and they did spec test twice, ? I think that might have triggered labour? , had normal delivery, discharged me before 24 hours, baby is still there, lost bit weight but back to 1.8 last night. Hopefully she do well in next few days and they send her home🙏🙏otherwise she is doing well🙏🙏❤️❤️
