I’m a little over 5 weeks pregnant and have had a headache/migraine since yesterday afternoon. I usually get these around the time I start my period so I am nervous that this could be a bad sign. This is more of an annoying persistent headache versus some of the more severe ones I get with my cycle. The last migraine I had was a couple weeks ago the day implantation occurred, assuming it was from a big shift in hormones. Am I freaking out over nothing? I know I can take Tylenol but I haven’t wanted to because it never helps anyway.
