conceiving issues

Ashley
So I'm still having trouble conceiving. It's been over a year and in that year I switched doctor because the Doctor iv had for 8 years and delivered both by children was not helping me what so ever. This new doctor is great and has run serveral test on me but everything is coming back normal. My kids are 7 and 8 and I had no problem conceiving them so we thought maybe its was my husband (children are from a previous relationship) but everything came back normal. Now the doctor is saying I need to loose weight. But that's not working either. I'm eating healthier and less and working out but the last 2 months I have stayed at my exact same weight. Any advice on what else I can do?? Please help.
