Chemical pregnancy

last week I was writing to find out if a faint second line means I am pregnant. Later I took a clear blue and results were positive 1-2wks. But then I got my period. I believe this is a chemical pregnancy and I see why people say to test after your missed period. perhaps I wouldnt have known this happened. Has anyone else experienced a chamical pregnancy and got pregnant quickly after? They say it's a good thing because you know you can get pregnant. But wondering if others tried the month after or were told by their doctor to wait a month before trying again?
