Two c-sections do i have to have a third or can i try for a normal delivery?

i had both my children via c-section first one emergency second one was elective, which i decided to do after a horrific first labour experience, looking back if i had of had more information i probably would've reconsidered the second c-section and tried a natural delivery as those two were 8 yrs apart and the risks were significantly lower because of the gap, and the thought of a third child was never an issue as i suffered with endometriosis and never thought id have a second, due to that being cured from the pregnancy my husband and i are now discussing a third child, in approx 2 yrs at the most, due to my two cesareans will i have to have a third c-section or can i try for a natural delivery taking into mind there will be only 2 1/2 yrs in between does the time in between matter? are the risks higher because iv had two should i consider a third? by that time i will be in my 30s does this matter?
