Twins and Multiple Pregnancies
Hot FlashesHot flashes (or, in official 'doctor speak,' vasomotor flushes) are a common side effect of Clomid, with 10% of women experiencing them, according to clinical studies. When you’re having a hot flash, you may suddenly feel extremely warm, experience face flush, break out in a sweat, and have a more rapid heartbeat. After a hot flash, you might feel chilled (especially if you broke out in a sweat). Hot flashes are also known as night sweats if they happen while you’re sleeping. A hot flash can be a bit unnerving the first time it happens, but it’s not a dangerous event -- just an uncomfortable one.
Bloating and Abdominal Discomfort
Weight GainWeight gain isn’t as common as bloating, with less than 1% of women reporting weight changes while taking Clomid. But it’s a side effect that you hear often through the infertility grapevine. If the weight gain is connected to bloating, then your weight should go back to normal after treatment.
Nausea and DizzinessAbout 2% of women experienced nausea and vomiting while taking Clomid. This is another side effect, which may be lessened by taking the medication in the evening. If the nausea is intense, or you have trouble keeping down food and fluids, be sure to report this to your doctor. Severe nausea can also be a sign of ovarian hyperstimulation syndrome, a rare but potentially dangerous side effect of fertility drugs.
Abnormal Menstrual BleedingJust over 1% of women in clinical trials reported spotting, or abnormal menstrual bleeding, as a side effect of Clomid. This can drive some women crazy, since they see spotting and think, “Oh, it’s implantation spotting!” But especially if you’re taking fertility drugs, the spotting in the middle of your cycle can be related just to the drugs and doesn’t necessarily indicate pregnancy. If the spotting is accompanied by other symptoms, like abdominal pain, nausea and vomiting, or fever -- or something just doesn’t feel right -- contact your doctor.
Breast TendernessBreast tenderness is another potential side effect of Clomid, occurring in 2% of women during clinical trials. This is another side effect that can have women wondering if they’re experiencing early pregnancy symptoms, but usually it’s just a drug side effect.
Vaginal Dryness or Thick Cervical Mucus
This is a frustrating potential side effect of Clomid, as thick or absent cervical fluid can interfere with achieving pregnancy. Cervical mucus is needed to help transport the sperm into the cervix. If Clomid causes thick cervical mucus, this can decrease the chances of getting pregnant. You should let your doctor know if this happens during treatment. He can consider whether Clomid is the right drug for you, or find a way to treat or bypass the problem (like with IUI treatment).
