Rummanah

Hi everyone ok so, this is the thing, I have two gorg boys 5 and 7 and had a miscarriage with baby boy in November 2013 and miscarriage with baby girl in July2014 and now my period is every 3 weeks and have been trying again for 2 months now

I was due yesterday so I done a test and was negative, so I done another one today and was negative again... My periods are mostly spot on so im very confused.

Any help?
