Your age is the biggest factor in trying to get pregnant. At age 45 your chances of getting pregnant is <5%. Because of this, I suggest seeing a specialist called a Reproductive Endocrinology and Infertility specialist who will check some blood test call a cycle day 3 FSH, LH, Estradiol, Prolactin and TSH. The cycle day 3 FSH gives you an idea of how old your ovaries are or ovarian reserve. At at 45 we expect that your ovaries are older and your eggs are older and therefore they will have a harder chance of fertilizing and greater chance of having chromosomal problems called aneuploidy. This is why I suggest seeing a fertility specialst as soon as possible.
