Scared of another miscarriage

Tasha
I have been having some cramps, and some other early pregnancy symptoms. Yesterday I noticed my breasts were really full, and of course painful. Today I wake up to my old boobs, no cramping, no nauseous feelings. I am scared this is going to be miscarriage #4.
Ugh I wish I could have gotten my hcg levels back Friday. Wednesday they were at 138.
All those numbers will be out of date by the time I get them anyway. 
I can't do anything so I need to relax about it but it's hard. 
Suggestions?
Thoughts?
