Anyone find it hard to convince after twins

I had twins almost 5 years ago they were born at 38 1/2 weeks via emergency c- section because the one decided to lay transverse at that last min. Anyway I'm now TTC for a second pregnancy 3rd child n its been over a year almost two years I know that huh having a c section can sometimes make it hard to convince but is that fact my first pregnancy was twins also a factor anyone with the experience please respond .
