Oh wow! That's got to be terrible! CALL YOUR DOCTOR NOW OR GO TO THE ER
Ok, here's the really hard part...it MAY affect the baby and cause some problems, so YOU NEED TO CONTACT YOUR DOCTOR IMMEDIATELY! Even though you've only had the symptoms of chicken pox right now, it has taken 4 weeks to develop inside you. Here's the link where I found out that there might be complications for the baby and the information is copied here:

Pregnancy and Baby Dangers From Chickenpox
Serious complications from chickenpox are uncommon in children, but 11 percent of infected adults, including pregnant women, develop a dangerous form of pneumonia. And babies of infected pregnant women face a small risk (2 percent or less) of congenital varicella syndrome, a group of birth defects that can include scars, muscle and bone abnormalities, paralyzed limbs, a small head, blindness, seizures, and even mental retardation.
Another risk of chickenpox during pregnancy is that the infant may contract it. If the mother develops her chickenpox rash between 6 and 21 days before delivery, her baby's case is likely to be mild and require no treatment. But if the mother's rash develops later — from 5 days before to 2 days after delivery — and no steps are taken to shield her fetus, the newborn has a 25 percent chance of getting chickenpox between 5 and 10 days after birth. It might be severe: Up to 30 percent of infected babies die if not treated. Fortunately, dangerous newborn infections usually can be prevented, or their severity lessened, if the baby is treated right after birth with an injection of antibodies called VZIG (varicella-zoster immune globulin). If the baby develops symptoms in spite of treatment, new antiviral drugs can help reduce the infection's severity.
Some studies also suggest that chickenpox in the first 20 weeks of pregnancy increases the risk for preterm labor. If you haven't had chickenpox or aren't sure, take steps to protect yourself and your baby
Preventing Chickenpox During Pregnancy
If you're not yet pregnant, ask your doctor about getting the chickenpox vaccine, which has been available since 1995. Your provider will first test you to see if you're immune to chickenpox; about 85 percent of women who have no history of it turn out to be immune. In the event that you do need the vaccine, you should wait at least three months after receiving it before attempting to conceive.
If you're pregnant and have no history of chickenpox, your doctor will probably recommend a blood test during a prenatal visit. If the test shows that you're not immune, you should avoid anyone with chickenpox and any susceptible individual who's been in contact with an infected person. If your susceptible child was exposed, call your doctor for advice about what to do.
If you're susceptible to chickenpox and have been closely exposed to someone who has it, contact your doctor right away. He'll probably recommend treatment with VZIG (which is safe for you and baby) as a preventive measure. It's not yet known whether giving VZIG to a pregnant woman helps protect her fetus from infection.
Mostly children get chickenpox, so this is for kids, but here's an excerpt from a page to help you out with the itchiness. You can also talk to your doctor about anything else he might recommend.

To help ease the symptoms of an uncomplicated case of chickenpox, follow these simple self-care measures:
* Don't scratch. Scratching can cause scarring, slow down the healing process and increase the risk that the sores will become infected. If your child can't seem to stop scratching, put gloves on his or her hands, especially at night. And trim his or her fingernails to lessen the amount of damage that can be done. If itching is particularly severe or irritating, talk to your doctor about prescribing an antihistamine for relief.
* Take to the tub. Comfortably cool baths can help relieve itching and provide a playful diversion for a young child. For added relief, sprinkle the bath water with baking soda, uncooked oatmeal or colloidal oatmeal — a finely ground oatmeal that is made for the tub, not the stove.
* Apply lotion. Dabbing the spots with calamine lotion may help relieve the itching.
* Try bed and a bland diet. Getting plenty of rest can help beat any infection. Soft, bland foods can also be helpful if chickenpox sores develop in the mouth. Spicy, acidic or hard and crunchy foods can be irritating to mouth sores.
* Treat a fever. Acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) won't cure chickenpox, but either medication can lower a mild fever. Don't give aspirin to anyone with chickenpox because it can lead to a serious condition called Reye's syndrome. And don't try to treat a high fever without consulting your doctor.
