Help !?

Any ladies have something similar happen?? Ive been having cramping since 4dpo started on left side then at 5dpo into lower abdomen and bloat and been quite steady ever since. Last night and today (7dpo and 8dpo) I’m having pretty bad cramping feels like AF is coming and so bloated but I’m not due for my period for another 8days. Also had a big “blob” of clear discharge this morning that had a bit of brown blood in it. Never had this before I’m just wondering if anyone felt that before getting a bfp if not I’m a little concerned something is wrong. Thanks 🙏
