I am having my fourth baby just found out im 7 weeks pregnant. Im 36 and had my other three children in my twenties so Im finding things very different this time. Im having symptoms I have never had like morning sickness and cravings and im so tired all the time nodding off as soon as I sit down. Im getting a lot of tummy cramps as if Im going to start a period is this normal ? I dont remember having this with any of my others . Many thanks if anyone answers xx
