Depression from seeing a negative test


My so and I have been ttc but every time I take a test it comes back negative and it’s starting to really make me depressed. This time I showed so many signs that I never have when my period is going to happen. My breast have been hurting for almost 2 weeks now and the most they ever hurt is 2 days before. I have been using the bathroom a lot more and my clothes have been started to get really tight but once again a negative test showed up ugh.
