3 weeks late

Ar

Hi! I am three weeks late and just took a HPT since the stress was eating at me. The result was negative (currently avoiding pregnancy, so I am relieved). The only chance that I could be pregnant would be from precum. We started out without a condom but stopped the deed to use a condom. It was a few days before my fertile window. Currently in a long distance relationship until our wedding in a few months, so I've got my dates down and well documented. Do you recommend retesting, and if so, when? I'm "irregular" but never go past 40 days or get my period before 30 days. Booked an appointment with my OBGYN, but she is so busy that it will be a while until she can see me. Thanks!
