Well, there I was anxiously awaiting the new STS system to get to an all time higher fitness level when.....I realize my period is a week late, did an EPT and SURPRISE its positive!! I'm of course thrilled but very nervous, because before my twins were born 4 yrs ago (whom I needed help conceiving using fertility meds) I had a history of miscarriages and hormone issues. I pretty much gave up on having more children thinking I couldn't or it would never happen "naturally". Now, needless to say, I'm living moment to moment afraid of something bad happening. My Dr. appt isn't until July 15th. I sort of layed off working out, so I can't blame myself if anything happens. I've been having intermittant headache, very mild cramping, and incredible lower back pain. Then there are other times I feel totally fine and would like to work out..but I don't. I'm figuring I'm about 5 wks pg. Thank Goodness no spotting. Anyone else ever have the back pain issue so early on? Any words of encouragement would help!
