why are my so jealous??

I lost my baby three months ago, due to heavy bleeding and pain in the ovary area, i was looking forward for my baby but it didn't work out, it's been three months now i'm still trying and nothing happened i don't know why its taking too long, but every time i see a pregnant woman passing by i get so jealous and hurt, i wish that it was me and my boyfriend who's been very supporting is affected by it too, i just wish that i was still pregnant so that i would not be feeling like this. how can i get pregnant fast, me and my bf have been having sex almost everyday, i'm so desperate.
