Tell me how to use preseed and soft cups

Amanda • I am 23, engaged to be married, our first is a beautiful 5 y/o angel in heaven, We lost her April 2015, miscarried our second October 2014, we are waiting for our rainbow after the storm. (Ttc 2yrs)
I see it a lot and I am desperate to try just something! BC I have been TTC for 2 years now! Conceived after a year then miscarried at 13 weeks, then lost my precious only child bc of a doctors careless mistake. She was only 5 and she was my world, I don't like life at all without being a mommy!😢
