Just looking for advice or to see if anyone has ever experienced this. I am now 19 dpo, period is 5 days late and I just feel like crap. Had light brown spotting for 3 days before my period was supposed to come. Got a bfn on 14 dpo and tested again 2 days ago and still bfn. Woke up this morning super nauseous, lightheaded and fatigue. Can’t eat anything because my appetite is non existent. Not sure what’s going on and can’t get into my doctor until Dec. 2. I am also having very light cramping
