advise please

currently trying TTC #2, have been trying for 8 months. have irregular periods sometimes, am currently 9 days late for this cycle.. could be just an irregularity.. but I feel pregnant. keep getting bfn. have sore breasts- feels like a let down feeling when you breastfeed, mild nausea, really moody, bloating and cramping.. things I don't normally get with my period. anyone else experience anything similar and get their bfp?
