Hi everyone! 
I have been married for 5 years for the first time my husband & I have been trying to convince it's been about 5 months nothing yet . Sometimes my period is super late & I have the symptoms sure enough I take that test & im disappointed! :(
I'm 28 & im ready for a baby 
What are you opinions ? How long does it usually take to get it right ?
Thank you
