Hello,
Sounds like a normal complaint of early pregnancy. Best regards, Dr. Downing
In the first trimester I felt very tired and flu like for a few weeks. I am currently pregnant with baby #3 so I would say your symptoms are very normal. If you start to run fever, pass blood, or feel sharp pains I would notify the doctor; otherwise, just try to sleep as much as possible and rest.
Im 8 wks and three days and feeling achy is very normal. back pain is real normal too. Dont worry to much!
