I’m so confused

So af was due 1/8 but I have irregular periods. On 1/9 I took two test that both came out vvf but you definitely can tell the second lines were there. Then everyday since I’ve got nothing but bfn. I’ve have sore boobs, a little bit of some I guess creamy cm, headache, and nausea. I always take pt with fmu. Idk please some one give me some advice or options idk what to do it’s driving me nuts.
