3DPO cramps, nausea, gas, heightened sense of smell

Really strong cramps and twinges that come on and off in the central lower abdomen area and shoots down towards my vag. I’m only 3DPO and I know it’s early still and 16 days left to my period. I know I O’d earlier this month. Also pains in my pelvic and hip areas, heightened sense of smell. And noticed tiny little red/brown specks when I wiped today. I know it’s not a cyst cuz I want to my gyno for an annual a month ago.

Hope it’s a good sign. Baby dust to all ✨✨✨
