already have one child, now trying ttc again with no luck!

Have you seen a fertility doctor?? Or an Obygn?? It may be that there is too much stress going on. (Not sure) I think you should try ovulation tests. Maybe that will help. I wish you luck!!!

Im in the same situation, i am 25, i have a 3yr old son and have been ttc for 18mnths. i had a 'chemical pregnancy' ( a very early miscarriage) last week and am wondering what i can do to get pregnant, and stay pregnant! That is my second miscarriage! i also have pcos so that is why it is harder for me. i would advice getting all the infertility test out of the way, that will put your mind at rest and once you know something is being done you may relax more and that will increase your chances of a successful pregnancy. thats the road i am currently going down anyway! I wish you luck,
