I just don't understand

Is it normal to be jealous of people who tried for less time and have results? It fills me with resentment for them... I don't want to feel that way. I feel horrible that i do... But i see all around some women who didn't even try, who weren't even ready or prepared that are pregnant... All i want is to be a mommy. To hear little giggles and kiss little fingers/toes. I've never wanted anything else out of life.. The doctor recent had a blood test drawn because i was showing a lot of signs my boobs are still huge and sore my periods been weird lasting longer than usually and so baby more but nothing... I just don't understand...
