Cant concieve

I have been trying to get pregnant for 7 years, I was pregnant one time in my life at 18 and had to terminate the pregnancy. I feel as though that ruined my body for since then I have never been able to concieve my partner and I have been following my periods and ovulation to the tee but nothing ever happens I was 5 days late on my period then this morning I woke up with it.. Ughh I'm so frustrated with my body its so discouraging! Anyone else having this problem.??
