Can Valium,benadryl And Ibuprofen Cause Any Side Effects During Pregnancy?

Hi, Three months ago exactly I fractured me L1. Today I took an at home pregnancy test and it was positive. I m scared and I don t know what to do, aside from that I m not sure how far along I am and I have been taking a number of medications either prescribed or recommended by my dr while neither of us knew I was with child. Over the past few months I was taking loritab and Valium several times a day, I stopped about a month or so ago. Since I have been taking lots of ibprofen and benedryl. I read that ibprofen can cause birth defects when taken in the first trimester and I m worried. Also I m in a lot of pain all the time from my back, is my back going to continue healing while I am pregnant? Is the additional weight going to hurt my back more? Have I hurt my baby by taking all of this medication? Is this a high risk pregnancy? I am going to make an appt with a dr as soon as I wake up, it was to late by the time I found out today. I ve never been pregnant before and this is a pretty unexpected confusing and worry some situation. I dont know if its helpful, but i m 27 years old and im a vegitarian, also i dont have health insurance and i havent been able to return to work yet. Any advice or guidance would be greatly appreciated. Thank you so much J
