Im jessica and im 22. I got this app to track my cycle because I have had trouble getting pregnant due to an std that went untreated when i was 16. I know my chances cannot get better as I get older and I am so worried... does anyone have any tips. I am generally healthy. 5'2, 120 #. I try to eat healthy and exercise. My momma says it will happen when the time is right. I cannot depend on that after trying for so long....
