Having no symptoms but BFP

Victoria❤💜

Hi y’all. My last period was July 27th. I have missed my period for august & looks like I will this month. I took a test Sept 18th it was negative. Today sept 23rd I took three tests came back positive . But I’m absolutely having no symptoms….and I don’t know how to calculate how far along I would be now? I’m going to the docs next week.
