I am 25 have two children 6 and 5. Me and the hubby want to try and have one more. My period is very irregular. I had it on March and then just had it for a week last week. I have been having dizziness issues for 2 years with bad anxiety. Dr wants me to get mri and grt pituitary gland tested. Should we try to get pregnant or wait a while. Oh I am also overweight a bit I am about 190lbs...please i need opinions!!!
