Thanks for posting your query.
From the information you have provided,
You are having
High BP in
pregnancy. The medication is
nifedipine which is commonly prescribed and safe in pregnancy.
You doctor might have told you that the definitive treatment for
pre eclampsia or high BP in pregnancy is delivery. As you are only 33 weeks , we will try to take your pregnancy as far as it will go . During this time, we will give
steroid injections for baby's maturity (particularly lung) as there is a chance of early delivery.
The symptoms like headache and lights in eyes could mean severe
preeclampsia. These are warning signals & you need to see your doctor immediately.
You will be admitted, blood tests will be done to look for blood counts, liver and kidney function tests, scan will be done to look for baby's growth, fluid around and blood flow (doppler). Your BP also will be monitored and medicines given accordingly (tablets/injections).
If your BP is not settling or if blood tests are abnormal or if baby is not happy , then we will have to deliver you immediately. At 33 weeks it will mean
caesarean section. After 36 weeks we can induce labour.
So, please meet your doctor as soon as you can.
All the best, take care!
