getting discouraged

Well another month has gone by and still not pregnant.  Went off birth control last Sept., miscarried in late february at 7 weeks, and here we are now, June and just got my period.  We have intercourse everyday,  I just want to conceive already.  I am trying to stay in good spirits but I constantly think about it.  My co-worker says stop trying it will happen when it should, but it's all I think about.  Someone suggested one of those ovulation tests, but I really don't see whats the point when we have intercourse everyday anyways.
