Smh getting frustrated opinions please

First, Happy New Year everyone. Now here a crazy story. Around Halloween we ttc. It was during my ovulation week. In November I had some spotting for 3 days close to the time for af but it stopped on the third day. Ok, so all of December I've had nause throwing up tender swollen boobs some pressure and some mild twinge of pain on my left side. No af and no bfp. These tests are super expensive and I'm tired of buying them😔. I did have one faint line that showed up after 5mins but that's it. Please help #frustrated
