It depends if you've been on the pill previously. I was on the pill for 8 years, and I stopped taking it 12 months ago. Sometimes it takes people longer to fall pregnant if you've been on the pill for awhile before you stopped taking it. Also make sure you're having sex when your most fertile, this app definitely helps track that. I've been told make sure after your partner has ejaculated to keep your legs up so that the sperm actually ends up inside you
