when to try

Brittany

my period this month was 28 days late and I'm so scared. I had cervical cancer in the past and was told I may not be able to conceive but that we wouldn't know for sure until we tried. we've only been trying for a few months but with my first two kids, pre cancer, I conceived right away. this time feels different and so much harder. how do I know what days to try and what days to not? how do I keep hope? Help!
