trying things out

I'm Brittany I'm 24 almost have 1 child my husband and I have been trying for 11 months so far to have our 1st child together. I have still a weird period even with being on the Implanon birth control last year and getting off last september. my husband and I did have a miscarriage a couple months ago so we're still recovering from that but our sex life hasn't been bad, it's slown down due to his job, and us moving (&stress) but not very much. like normal couples we've gradually gone down from our first time (almost every day we were together for a week) my husband is also away from me for about 10 days at a time but from our first to now it's about 2-3 times in the week he is home. and as far as my last period June 13th it only lasted bout 4 days and then the following Thursday I had light spotting. I have not taken a pg test recently, I'm waiting to see if my period comes this weekend or not and if not then I'll probably take one Monday or tueaday. I'm just trying to figure this entire thing out since having my first child wasn't planned and I didn't pay attention to what really was happening to my body or anything for myself, just my baby. so now almost 5 years later I'd like some help in knowing how to becoming pregnant / becoming. more fertal so I can become pregnant.
