excedrin migraine in second trimester?!

So my doctor told me I could take excedrin migraine for my headaches and never said how many to take or not take and I assumed just following the instructions on the bottle would be fine. Well I took a second dose for the first time today six hours after my first. These headaches have been killing me. I then looked up the amount of aspirin in one dose of excedrin migraine to find it was 250 mg which is a decent bit higher than the 60 to 100 recommended online. So that means in one day I've taken 500. I'm kind of freaking out and honestly I don't think I will even take excedrin once after this but will it be okay? I am 5'8 and a solid person so I normally get higher doses of things but I can't find any research on aspirin in the second trimester only first and third. I'm twenty weeks but I'm just so anxious now for my little girl.
