We should all keep this in mind. I know we all want to see a BFP as earlier as possible, but it may not be a good idea: Chemical Pregnancies Human reproduction is not an efficient process. It is estimated that in nature only one out of every three fertilized embryos results in a livebirth, and that the monthly chance of a baby being born to a healthy couple, with the woman in her prime fertility age of 24 to 27 years old, is only about 7% per month. This is why we define infertility as one year of attempting conception without success. During that year, about 90% of couples without problems will at least begin a gestation. Almost every s_xually active woman will at some time notice that she has had a change in her period, a few days late, a slightly heavier flow, and perhaps more br___t tenderness than usual. If these women have been previously pregnant, they often will state that they felt as if they were pregnant again, but then they had their menses. If they had done a pregnancy test at home or with their physician they often had a positive hCG level that turned negative. This is known as a biochemical pregnancy, and represents an early pregnancy loss. When a women is late for her cycle, she may have ovulated late, not ovulated at all, or at least begun a pregnancy. The positive pregnancy test confirms fertilization, and implantation, but essentially nothing more is known. The pregnancy could have been in the uterus, or in the tube (as most tubal or ectopic pregnancies also “miscarry” dissolving in place or are expelled out the tube). It is critical that the pregnancy test be followed until negative, even if the women notes a period, as tubal pregnancies are often accompanied with a normal or abnormally timed menstruation. What causes a chemical pregnancy to occur? Most of these represent early losses, “quality control miscarriages” due to chromosomal problems in the developing fetus. An abnormal endometrial lining, uterine abnormalities both congenital or acquired like fibroids, or certain infections have been blamed for these losses. The role of antibodies or coagulation problems may be a factor, but these are rare, still controversial, and are unlikely to cause such early losses. When undergoing infertility therapy, an injection of hCG given to induce maturation of eggs and follicles or ovulation is frequently given. The levels of hCG may circulate for up to 10 days after the shot, and a pregnancy test done too early may give a false positive. Pregnancy tests need to be properly timed and interpreted. Home urine tests are not always correct- they can give false positive and negative results suggesting a chemical pregnancy. Very rarely, hCG made from ovarian cysts and other body tissues may give positive tests when there is no pregnancy. How should you feel when you are told you have a biochemical pregnancy? Some people are happy that at least the first steps toward parenthood have been confirmed, while others now worry that they are having recurrent miscarriages or that they will have an abnormal baby. In our practice, our patients are told that we have only one goal- a normal healthy baby. Chemicals pregnancies do not count for or against your chances of us celebrating that event with you. If you feel that this is happening frequently to you, especially if the woman is over 35 and you have tried more than 6 months, discuss this with you doctor. A basic workup should be completed. Best of luck! Abington Reproductive Medicine.
