“Are swollen glands during pregnancy normal?”

If you mean breasts the answer is yes

It can be strep throat or tonsillitis. Normally, swollen glands are not common things seen in pregnancy.

Swollen glands are a reaction of the immune system in a regional area; reactions can occur against inflammation that a local tissue reaction cannot handle easily such as a large area bruise. However, most ‘swollen glands’ are a reaction of the immune system against an infection; if the immune system can handle it locally, then glands do not get recruited. If the infection is larger or the immune system needs to recruit ‘more helpers’, then it will call in ‘more troops’ and the lymph nodes will reflect that increased activity. However, when something goes awry in the lymph node, or a problem cell that actually turns cancerous in a lymph node, then that node can get overridden with those cancer cells; this is called lymphoma. Despite pregnancy being a 9month time in a woman’s life when she is doing something that her body may have not done before and her immune system may not have seen before, the body does not typically ‘attack’ the fetus or pregnancy so the immune system is not sensitized to the pregnancy tissues or the fetus so there is not a typical ‘swollen gland’ reaction by the body.
