Hi dear , I have gone through your question and i understand your concern. Swollen labia is pretty common. You have increased blood volume due to the pregnancy and this can casue swelling. In most cased the pain/swelling will go away and it will help if you lie . bumps you have are pregnancy related, they will get smaller and fade after the baby is born, so you do not need to worry of them unless they are uncomfortable. Under circumstances itchy,discharge or any additional signs/symptoms I will advice for direct clinical examination. Rest all don t worry, be happy & feel light. Wishing happy time ahead. Hope you find the answer helpful, please do get back for further queries I will be happy to assist you. Rate 5 stars for clarification being satisfactory. Wishing your good health.
