Recent studies have shown that you can start trying again immediately after a reason why some doctors will tell you to wait for your first cycle is so they can have a more accurate due date. You can try again and have a healthy pregnancy about 50% of all pregnancies end in miscarriage and your chances of having another one are unlikely unless you have a medical condition. Best of luck.
Sorry for your loss. You would be better wait a few cycles before ttc again, so your uterus could recover well for another pregnancy. I had an d&c in January and got my first period only in April. Waiting now for my third period to start ttc again and look.. I`m 39 years old.
You are very young, you have plenty of time, don`t rush things. You should think if a pregnancy is really what you want, it will not be a solution for your abortion regret. In my opinion you are too young to have a baby, let live your life, study, work, travel... Not saying you should wait so many time as I did.
Hope you the best. xx
