I agree with tarajanes...and fertilityfriend is a great site!
Hiya secondary infertility is very common,im 35 and have a 15 year old son,we have been trying for several years.then we sought fertility treatment,we tried clomid,yes its normally given to induce ovulation,but its also used to help get a better ovulation,this worked for us we ended up getting pregnant 4 times but suffered loses,but goes to show it can work,other than what your doing do you chart,although you may get positives on ovulation tests,this doesnt mean you ovulated.only charting would confirm you did,i would consider this if you havent,check out fertility friend.com or ovusoft,really good sites for info.i wish you the best of luck..
