Hello My Name Is Megan McNea I Am 20 Years

Hello my name is Megan McNea I am 20 years old and I am wondering if it is possible I am pregnant. I have been having frequent Migraines. I have also been feeling pretty sick. I have gotten very weak and tied a lot. Also I eat a normal amount to counteract Hypoglycemia and it has recently started to not be enough. I am very concerned. Also my breasts hurt very badly. My soon to be husband can not even touch them anymore without me being in pain.
