I know exactly how you feel. In the first year after my tubal, if I was more than two weeks late, I went for a pregnancy test. My periods were irregular my whole life, so I had a lot of pregnancy tests in the previous 11 years. After year one, I had a couple of tests, and by year three I was no longer worried. I was pretty sure with all the tests that I wasn't pregnant but I just had to be sure. With all my pregnancies I was best friends with my toilet for a few weeks in the beginning. I never had any of those symptoms after the tubal, and I realize now it was paranoia. It worked great for me for the next 14 years until I had a hysterectomy. Now if I have a child, it will be by a higher power. Good luck. That feeling really does go away with time.
