We have been trying for six months but no luck till now. Should we go to see a fertility specialist?

Agree with Jamie that 6 months is too short of a time to get panicky. 12 months would be a better gauge. If 12 months and you still do not have good news, you can consider In vitro fertilisation (IVF) which is subsidized by the government. You can a fellow mummy's blog about her journey with IVF. She has also blogged about the timeline & also the approximate cost of it (plus government help). http://deardyan.com/category/ivf-journey/
