I just want to be pregnant already....

I been with my man for 4 years and finally we have decided that we want to have a baby to complete our family. I have 2 children and he has 1 all of them are from other relationships. We just think now is our time. I had a miscarriage Aug 13 2017 at 5 weeks and crushed our heart. I been trying to track when I ovulate but I'm not sure how long my menstraul cycle really is...lol. it says I ovulate on the 20th and was fertile the 16th -21st we had sex everyday so now I'm just waiting and hoping for a positive test. I started cramping today thinking AF was coming and we failed but no I'm not bleeding which is great. This app states I should start my period on the 3rd based off a 26 day cycle so I'm just praying for a positive test..... this 2 weeks is no joke 😣
