For those who got a bfp

Hello ladies :) did anyone use soft cups the month they got their bfp? I thought soft cups were only for when AF is here but some woman have said they used soft cups and got their bfp. Is it because it keeps the sperm there for longer so you can conceive? Just curious as I'm ttc and have been for 11 months and if this cycle doesn't work I'm considering trying other things :) thank you in advance!
