Just curious if anyone else on here has made the connection between taking pre-natal vitamins and headaches. I am approx on CD 12, and have a mild headache for weeks. It isn't bad enough to take a pain reliever for, however it lingers and fades throughout the day. Before taking the pre-natals, I rarely had headaches (except after getting tipsy the night before!). I remember taking regular vitamins about 4 years ago, and they gave me headaches, similar to this. Now, unfortunately, it looks like the pre-natal ones are also I've been taking the vitamins randomly, whenever I remember, usually one a day, sometimes one every other day. Any ideas or suggestions on these headaches? I don't want to stop taking them, because obviously they are important! Thanks!
