Well I am not sure I have tips exactly but I can tell you what happened with us.
We magically conceived in our first month trying. Some of this maybe TMI haha!! Form what I can tell it was one of 3 times that we conceived. I knew roughly when I was ovulating due to CM and stuff but no OPKS or anything as I didn't wanna be

just when I got a positive OPK. So we were in the mood and basically

every other day around ov. The first time was at my inlaws

on their sofa! Hubby on top, just used saliva on each other

ha, which I know is not recommended. The second time, we didn't even have foreplay actually, I was "ready" just sucked hubby

and jumped on - me on top! The third time was pretty much the same. So basically we did it when we wanted, how we wanted and enjoyed it - relaxed and fun - exactly how I wanted to conceive.
I was worried because both me and hubby are overweight and so I thought we would take ages to conceive. So I really believe that we are so so blessed!! My whole family seem to be very fertile and all I can say is that I guess we must have been extremely good with contraception (mainly condoms) for the past 8 years!!! Oh and I have been off the pill for over 3 years so I don't know if that helped too?
I am not sure if any of that will help! Good luck! xx
