Medications before finding out about pregnancy

So I was out of the country during my 2 week wait. During that time, I had an allergic reaction rash to a plant in a garden. I ignored the rash in case I was pregnant. At 9dpo I started spotting. I had been having early spotting for months after stopping birth control. So I thought I’d just started the normal spotting for 7-10days leading into my period again. So in the next couple of days I had taken 2 doxycycline pills, 1 hydroxyzine hcl, and 2 dexamethasone 2mg pills to help with the terrible rash. Then I decided to stop everything til I got back home. So these meds were prob taken at 9&10dpo. When I got back home I found out I’m pregnant. I’m now 8 weeks pregnant but until I can take the abnormality blood test I’m just freaking out hardcore. Does anyone have any knowledge on if what I took/how much/when I took it could be harmful to the baby? Just trying to remain calm 😩
