I have been trying to get pregnant since November (for about 5 mths) with no luck. I have been following the ovulation chart on my app, I've done a little bit of research as well, knowing sperm can live in the vagina for 24-48 hours. The only thing I have not done was buy an ovulation kit to know the exact time I'm ovulating. Being that women/couples get pregnant without it, what else could I be missing or doing wrong?
