Hello, I would be happy to help you with your question.
Given the fact that you only have one tube (even though it is open) and the fact that you have been trying to get pregnant for a year, my guess is that your symptoms are not related to pregnancy
. That being said, you need to check a pregnancy test now and again in 1-2 weeks. If these remain negative, then your symptoms are likely cycle related.
I hope that this helps. If you have more questions, please click on "ASK ME A QUESTION" link above to directly ask me a question!
