Help! My baby is huge!

Hello ladies, I need some feedback from those of you that had your baby already. How accurate is the fundal measurement? I just came back from my 36w appointment. I measured 38 and according to the chart baby is already 3.6kg!!! Midwife said the measurements are very accurate and to bring 0-3 months clothes to the hospital. I don’t care about this as I already bought him soooo many outfits from newborn to 6-9 month so I have all sizes; It’s just that he’s my first baby; I was already anxious about the actual birth, now that I’m thinking he’s going to be huge I’m freaking out even more... i cannot push a toddler sized baby through my vagina 😩😩
