Please help I have pcos but finally 10 dpo but not sure what’s going on .

I was diagnosed with pcos several years ago and have always suffered with infertility . This is the first time I’ve felt I can actually be pregnant and I’m going crazy . Around 6-8 dpo I was feeling off and pretty nauseous and having cervical mucus I also noticed on 8 dpo I had very veiny boobs and nipples seemed to have darkened slightly . I have also noticed more veins around my hips and lower belly . On 9 dpo I tested and got a very faint line . I had a head ache and back ache all day . it’s now day 10 and I tested this morning and noticed no line. 😭 still have the same symptoms as day 8-9 dpo . So I’m not sure . Please let me know what you think !
