Me and my boyfriend have been trying to get pregnant for 8 months what can i do to increase my chances?

Many things: 1. Don't stress out. 2. Stay in shape (weight loss, if relevant). 3. Smart sex: time vaginal, unprotected intercourse around ovulation (usually mid-cycle, but if not sure, use otc ovulation kit). 4. If you're doing 1-3 consistently for a year and still not getting anywhere, see an ob/gyn. 5. Have faith. It will happen; probably when you least expect it.
