Is it possible to get headaches daily from being on the pill?

Chloe
I used to be on the pill late last year until my partner and I started TTC #1 around February/March this year. 
But my partner has had to go away to a different state for a few months. 
So I've recently decided to go back on the pill while he's not here to keep my periods regular because they've been a couple days late for the past 2 months or so. 
I've been taking them again for about 5 days and I've been getting headaches each day and it's getting annoying. 
I never had this problem the first time I was on the pill. It's only been happening since I started taking them again. 
Is this what may be causing my headaches?
