I don't know about the low iron count, but if you are worried about that you could take an iron supplement and eat more iron rich foods. It really does sometimes take months and months to conceive. I'm not kidding when I tell you this, after you have sex lay flat on your back and elevate your legs on like 3 pillows so they are way up higher than you. It really helps. My friend and her husband tried for a long time. A nurse told my friend to try that and she got pregnant 2 months late. Hey, it's worth a shot right?
i have been trying to conceive for 9 months and nothing yet
it just takes some women longer than others
although 5 months may seem long to you its not really that long
you may want to start seeking help after a year of trying
