confused! advice/encouragement please!

My husband and I are into our second month of TTC. I'm 26 and he is 31. I stopped my oral BC in March. I had been taking for about 10 years. Last month I checked bbt and had positive opk. I had ovulation symptoms, including spotting. Then I had some light spotting before AF came along. I wasn't expecting to get pregnant right away but still was hopeful I'd be 1 of those lucky ones. This recent cycle I'm in I had positive opk and we baby danced during my fertile window (we've been trying to do so every other day in general) and now AF is to start Sunday. I've had some light spotting again this week. But I've also had other symptoms. I've had fatigue, back ache, I'm sensitive to some smells and have had some nausea, I'm also noticing increased hunger. I plan to take a pregnancy test tomorrow morning as I plan to celebrate cinco de mayo with some margaritas but don't want to if I'm in fact pregnant. Haha. But I'm just frustrated with this spotting. I never spotted before BC or during. And the symptoms I'm having are like nothing I've experienced before my period but I know it could be PMS (which my BC managed previously). I just feel alone because none of my friends know I'm trying and only a few have kids already so most can't relate. I'm just very frustrated with everything at the moment and I'm scared to take this first test for fear it will be negative. We want to start our family so badly. So any advice or encouragement would be great to help me get through this. Thank you!
