When trying to get pregnant, the most important thing of all is your health --both mental and physical. Your health is important all the time, but even more so when trying to conceive. Pregnancy is hard on the body, so avoiding these common things that are bad for you can go a long way.
This one is a no-brainer. Smokers statistically take twice as long to conceive! There is a myriad of other ways that smoking can affect your ability to get pregnant and once a pregnancy has occurred. Smoking can lead to premature births, birth defects, or even infant death. It's best to steer clear.
Weight Gain (or Loss!)
Any drastic change of weight can greatly influence your ability to get pregnant. Gaining weight once pregnant is inevitable, you have a person growing inside of you! But before you get there, entering pregnancy at a healthy weight is the optimal solution. Don't try to suddenly lose or gain any weight in association with trying to get pregnant --it's best to be done at another time.
Less of That Lube
Believe it or not, lube can actually slow down male sperm! Make sure you are using the right brand so as not to lessen your chances of getting pregnant. Lubrications are aware of these, and some offer alternatives that help instead of hurt. Look for the "sperm friendly" or "fertile friendly" labels to be certain. Pre-Seed is one of those alternatives that you can purchase on Amazon!
