TTC weird cycle still having "symptoms"

Jessica
My husband and I have been TTC for a little over a year. Last month I was feeling really nauseous at the end, cramps, tingling breasts and barely had any appetite. I ended up starting my cycle 3 days late which is weird because I am pretty regular give or take a day. My cycle lasted about 1.5 days and was really heavy. It's now been about 5 days and I am still realy nauseous, I have minor cramping and light pink discharge. 
Has anyone else experienced this? Not sure really what to think of it. TIA!
