Confusing times!

Summer

I’m feeling a little discouraged in my TTC journey. My period is 6 days late and I’ve never been late since I had my first period as a kid. I’ve always started the day I was supposed to. I’ve had a few symptoms (terrible acne, some nausea which only lasted a few days, and thick white cm) however, I took a PT today and got a negative result. I can honestly say I cried like a little bitch about it. I’m so confused and feel like my body is sending mixed signals. :(
