D..
So sorry you're having this, mama! Have you been to the doctor since they started? If not, go ahead and call the nurse and ask her to ask the doctor what you can do.
There are some really good medicines (prescription strength) for this. But the doctor will know what you can and can't use during pregnancy. The Tucks pads will help a little, but not a lot. Basically, it's witchhazel.
I really think that the doctor can help you more than the Tucks pads...
