TTC 2WW

Im 7dpo

I’ve had 3 negative hcg test’s on

5dpo/6dpo/7dpo

I have some symptoms going on including

Cramping/dull pulling sensation on left lower abdomen

Fatigue

Heightened sense of smell

But I’ve not had any implantation bleeding

Im not sure what to do or what this means as I’m at the beginning of my ttc journey

Any/All advice is appreciated

TIA🤍
