Loss of cervical mucus or secretions is common after surgeries like LEEP or cone biopsy, but it's not a baby deal-breaker. This fluid plays an important role (but not necessarily essential role) in providing nutrition to the sperm as the journey to the fallopian tubes requires a lot of energy.
The fluid is also protective because the vagina is a very cruel environment for sperm. The cervix has a much better pH for the sperm.
If you follow your cervical secretions to determine fertile times, it may not be possible after surgery. You won't have much mucus, and it may not really change during the month.
If you haven't been able to get pregnant after a year of trying and you're under 35 years old, it's time to see a specialist called a reproductive endocrinologist. If you're over 35, try for only 6 months before you seek help.
Now, some women with "hostile mucus" are told to use guaifenesin to thin the mucus. I have heard that works pretty well, but the difference is that they have mucus production. After cervical surgeries, you may not have much mucus because the tissue that produced it is mostly gone. So guaifenesin may not help. At the same time, it's harmless, so if you wanted to try it, go ahead.
If it turns out that the lack of cervical secretions is the problem, you can have intrauterine insemination to bypass the cervix.
Intrauterine insemination, or IUI, is where the doctor takes a really narrow tube called a catheter and pushes it through the cervix into the uterus. For some women, it causes a little cramping, but usually women feel nothing. Then the doctor injects the sperm through the tube. It's a quick procedure, taking just minutes. Then the patient lays on the table for about 15 minutes before getting up.
Now, one thing that doesn't change after surgery is production of the mucus plug during pregnancy. That is produced by the hormones from the placenta.
It may seem overwhelming, I know. But it should be reassuring that you will have options. And even if you need help to have a baby, you'll still have a baby.
