Did anyone have symptoms like cramping or lower back pain when you stopped the progesterone? I took 200mg suppositories the first 13 weeks and I stopped yesterday. All day today I have had mild cramping and low back pain. I am wondering if this is normal? My nurse said if I was concerned I should go to urgent care but I would like to avoid the expense if possible.. No spotting.. I know cramping is common in early pregnancy but this seems like af cramps.. And I haven't really had cramping before.. Is it just my body getting used to the change? Should I be worried?
