Hang in there! With all of the meds and the side effects it's hard not to look into every ache, pain, and moment... Try to relax and think positive.. if it gets too bad you may want to call the RE and see what they have to say. SSBD!
I had the same thing and same meds except I was on 2x100mg of prometrium suppositories 3x a day. I too had cramping and lower back pain, still do and I am 32 weeks pregnant today!! Good luck!!!
Hey how are you I had a 5DTF fresh on May 20th the weekend of my birthday the big "30", and I have my first appointment on Sunday 29 May 2011. I have no symptoms at all this is so strange, I don't feel anything but I am still hopeful. I am not spotting or feeling sick nothing. Well this should be a good sign and hopefully my birthday present. I will say a pray for you and GODS BLESSINGS to you hopefully it works out for you. Take care of yourself and keep us informed. :)
