TTC & cancer survivor

When we decided TTC about 6-7 months ago, I went to the OB to get checked to make sure that everything would be alright and brought up my past with cancer. My oncologist was always SLIGHTY concerned considering everything I had to go through, but the OB was the furthest from concerned at all and quite honestly wasn’t helpful at all. She told us to come and get “checked” in 6month-1 year if we had not conceived yet. Now the time has come that it’s been 6 -7months and nothing has happened. Should I just wait till the year mark to get checked? Or should I do it sooner rather than later??? Advice???
