Tips for pregnancy

Abigail
Can anyone provide some tips on getting pregnant! Me and my partner would love the opportunity to make a baby. I have been off contraception for about 4/5 months and still nothing! I think we are just not doing it at the right time. 
​I am using ovaluation tests the last few days and they are all showing negative. We had sex when there was a 8% chance of pregnancy! I am peeing more than usual, I have a lot of cm, and tummy cramps... Could I be at very early early stages!! I'm not getting a test till a week or so after my next period as I am sick of getting negative outcomes! Hopefully  this app will work! Does everyone take their temperature?
