do you think my prenatal is causing me to get daily headaches?

i’m currently 18 weeks pregnant and getting daily tension headaches. sometimes tylenol takes them away, sometimes it doesn’t. i noticed today i had a slight headache when i woke up, after i drank water it seemed to go away. then i ate and took my prenatal and bam headache it continued throughout the day and finally i decided to take a tylenol, and it went away for the most part. it was slightly still there. then i ate and took my prenatal and bam again a headache.

not sure if it’s related or not. wondering if this happened to any of you? if so, which one were you taking? what helped?

i’m getting headaches in the middle or the night at times…i’m waking up with them at times as well…but they usually don’t last too long in these cases. but when i get them after my prenatal, they last forever and sometimes tylenol doesn’t even work to take them again.
