Someone help😩

I don’t want to feel as if I’m overthinking but this is so weird. So every since 1 DPO I’ve had cramps every morning when I wake up and have to wait for them to leave before I get out of bed. Now I’m 4DPO, no cramps this morning but now that it is the afternoon, I wiped and noticed my discharge was thick (like the consistency of ovulation discharge). I have pressure on my lower abdomen, particularly my left side. It even sometimes hurt when I walk. Anybody else have these symptoms this early? Am I overthinking? Anyone received a BPF after having such symptoms?
