😱Wanna ttc for our third but scared

Me and my hubby wanna ttc for our third child but I’m alittle scared! My last pregnancy with my daughter I got sick and always felt dizzy towards the end. I’m scared my next pregnancy will be like this! I got preclampisa with both my kids in early pregnancy but it corrected itself but really scared about getting the dizziness again if we ttc! Should I be worried will my next pregnancy cause me to feel sick and dizzy to the point of almost passing out? I’d have to eat something sweet and than I’d go to sleep. I’ve told my obgyn last pregnancy and he said it was normal to feel that way.. my first pregnancy wasn’t as bad but my second was! Worried about having another baby....
