Hello, Thanks for posting your query, Normally when you are pregnant and you feel anything abnormal about your health other than pregnancy symptoms then you should definitely see a doctor. Feeling a lump in your throat or difficulty swallowing generally signifies that there is a swelling in your throat that needs to be cleared up either through medication or through surgery. I suggest that you should see a physician so your throat can be properly examined and the cause identified. The presence of red or bloody vomiting is a sign that there is a serious problem, probably an ulcer or a tumor or an infection. I suggest you should get examined soonest so that proper treatment can be provided. Hope this helps and wish you the best
