TTC❤️😭

So I've been ttc since August and I'm starting to feel very defeated. Is that normal this early on? I'm currently finishing up my tww and I bought a dollar store test that I plan to take in the morning. I'm so ready to see a + and so is my S.O. We are so excited for this journey. The only difference in this cycle from other cycles is I've sort of been experiencing period symptoms since I ovulated. Minus the bleeding.  Oh and I've felt a lot of odd light burning sensations in my uterus these past two weeks. Honestly though I just think it's all in my head. I'm trying to stay positive so I'll get a positive (haha riiiiight) I'm just a bit disheartened. Any advice?
