Sorry you're having to deal with these. I believe more often than not they lessen in frequency as you enter into the second trimester. For some they do stick around, but this is definitely the vast minority of cases.
During pregnancy I've read you can take some types of pain killers e.g. tylenol and specific narcotics (talk to your neuro first about both the scripts and OTCs).
I even read somewhere that you can take natural progesterone. I'm not too sure about the accuracy of this one, but I just thought I would throw it out there if you wanted to research it yourself.
I hope the appointment goes well!
