14 DPO

My cycle lengths are 28 days. I had unprotected sex TTC on the 2nd of January as I have another app that said it was my most fertile day. (I know that an app can be inaccurate) I had white creamy CM about 4-5 DPO lasting until today. Today it is watery, sort of creamy, and white. My cervix is high (I know it can change quickly) I have taken a few tests. All BFN. I’m due to see AF tomorrow but no usual symptoms for her... shall we say arrival? I have a son and I remember really apparent symptoms with him early on. I had really clear symptoms at first, but they’re diminishing. I am now experiencing really sore breasts, but that’s unusual for me to experience with AF, and I’m getting tired earlier in the day. Anything helps!
