Hello, I would be happy to help you with your question.
Most likely, these are symptoms related to your irregular cycles. Given the cycle irregularity it is hard to determine exactly when you are ovulating, so estimations of IF you are pregnant and how far along are difficult. Yes, these could very well be symptoms of pregnancy
. Check a test now and repeat in 1 and 2 weeks. Also, if you are not ready to be pregnant, then birth control for this reason and to regulate your cycle would be a great idea.
I hope that this helps. Good luck!
