17 DPO, BFN and no AF

Lauren

I am wondering if any of you lovely ladies can give me any advice, AF was due on Friday so now 2 days late, getting v v faint lines (or what could be indents) on FRER and CB, took a digital yesterday and it said Not Pregnant. Has anyone got a BFP quite late after testing negative for so long? I have a lot of symptoms, some which I don’t normally get for AF but neither have appeared so don’t really know what to think. Feeling disheartened so just looking for some advice? 😞🤞
