im 23 years old im a mother of 4 children i know im very young for so many kids but i would really like to settle with one more little boy before i cut my ties , im beginning a new long life relationship (hopefully) and he wants a child of his own and i want a child with him together before i get fixed , ive read about opk but have never used one in my life , my question is when is the best time to take a opk if trying to concieve? and if opk is positive when is the best time to have sex for better chances of concieving? im sure one of you mommys out there has awsome experience with this so if you dont mind letting me in on a couple of your secretes! so much thanks , sher ! .
