Anyone get the flu b4 their BFP?...

8DPO & sick as a dog 🤒 Uhg. for the last couple days I've been some what lightheaded and tired, this morning I woke up with a full fledged cold! Sore throat, head cold, pressure around my eyes, exhausted and just plain BLAH. I've been having light cramping in my right lower abdomen since 7DPO. IDK if it's implantation or not... last month I had stronger cramps @ 5dpo that I was sure was implantation, and that bitch AF still showed. lol. Anyways, I'm wondering if anyone experienced lowered immune system/cold and flu symptoms and still had a BFP? AF is due next week on the 17th. Thanks! baby dust to all my ladies 💗🌬️🎊
