This is my third month on vaginal progesterone, but today I am noticing some reder than normal spotting on a liner than normal. Normally I see some light color after taking the pill but today it seems to be a little brighter and in the same spot every time. Is this normal or should I be worried? I'll be 31 weeks tomorrow. Baby's movements haven't really changed but today I'm noticing a little more back pain than I have thus far during my pregnancy. I think I'm worrying myself more than I should but I just feel a little lost.
