idk???

My husband and I just started ttc last month. I had been on the pill for 2 years. I am irregular without it, but I am 14 days late from when I would have started on the pill. I have taken serveral tests starting off BFN then seeing a vvvfl. Yesterday I took a test and saw a vfl, but still visible. I took it on a clearblue. I had a two pack so I took the other one this morning and there was nothing. I'm so confused! Should I try on another test/set up an appointment with my doctor? I'm also showing different signs: nausea, sore boobs, headaches, tired all the time.... please help!
