I Am 28 Years Old. I Had An Ectopic Pregnancy

I am 28 years old. I had an ectopic pregnancy for the first time in 2013.
In 2014, had a normal uterine pregnancy and foetus got aborted in the start of 4th month. It was a Missed abortion.

I am not sure with cause of above abortion. I was told I am underweight.

I wanted to know whether I can get pregnant now and how to give birth to a healthy baby here after.
