Headaches

I was wondering for those of you that have headaches…my doctors told me that getting pregnant might actually help with the headaches. Which I honestly see no way that it will…if anything it would get worse right? Eventually I would love to have kids but I need to feel much better first. Any of you out there that had headaches and they got better with pregnancy? And did they stay better after you gave birth? Lol lots of questions. My doctors go back and forth a lot on what is causing my headaches. Sometimes they say it is because of the extra fluid and over time it will be absorbed and i guess pregnancy will help with that. lol. I dont understand that at all. lol. Anyone have any thoughts on this? Thanks in advance.
