endometrium Symptoms - side effects?

I have been taking endometrium suppositories and I am 6 weeks pregnant.
I feel hungry & nauseous and dizzy when I am on it. I called my place who gave it to me and they told me it was not from the suppositories. I stopped it last night, one dose just to see if my symptoms would go away or not and maybe the nurse was right. All my symptoms did go away and I am now annoyed that I have to take this suppository for at least another week and half. My level is 8.4 and they told me they need me to be 9. Have any of you also felt the same symptoms while taking this? Thank you!!
