BFN 6 DPO

I POAS this morning because I'm so impatient and got a BFN. 😔

Could I still be pregnant?

I'm still nursing my 19 month old. Just for nap time 1-2 times during the day and at bedtime. Not sure if that could affect anything? My DH and I want to expand our family so badly.

Any tips or advice for us would be greatly appreciated.
