Week 5 headaches

I’m not someone who regularly suffers with headaches, but this seems to be one of the side effects I am consistently battling with on and off.
How long is this side effect last on average. Has anyone else had this?

I always seem to get a headache that lasts a few weeks on and off but it doesn’t normally hit until around week 3-5 x it will pass normally by about week 6-7 it passes and happens less . hope that helps

I’m in week 5 now. That’s good to know. From someone who rarely gets headaches it’s pretty annoying. I will keep on plodding on through. Thank you for your response.
