Due June having baby in May

Michelle

Im due 8th June but due to me not being able to carry large babies and this little munchkin being the biggest baby ive ever carried Im getting taken in on 26th May for a c-section. Im nervous as with my other 3 whom are all teenagers now the youngest being 14 they were all natural births and weighed 6lb 12, 6lb 2 and 6lb 7. Anyone else had a big age gap between children and went on to have a bigger baby?
