19 days late! No BFP .. just very confused

I have had no symptoms of a period.

I don’t think I have any symptoms of pregnancy.. but I guess I am not sure what I am looking for..

I’ve taken a few pregnancy test..

I talked with my doctor she told me to go do a urine sample-which I did. It was negative

I haven’t been on birth control in over a year..

I am not stressed -I’m very relaxed..

I am sexual active ..

I am pretty healthy? I do not smoke or drink.

I am a little on the heavier side, but nothing seriously life threatening..

4ft 11in roughly 140ish probably 145 now due to quarantine (😂) ..

She suggested getting on birth control, but also suggested to pick up the prescription (the pill) and wait til after my period starts to start taking it ?

But what IF I AM PREGNANT.. I’m just all confused about it..

HELP
