5 day transfer tommorrow / progesterone is racing my heart

[wishing&hoping]

I just had my egg retrievel on Monday. I had 18 eggs which 14 were good quality,matured. 10 fertilized and they informed me yesterday that I had multiple high quality embryo's . So i am doing a day 5 blastocyst transfer tommorrow. I am excited but am having a bit of a reaction from the progesterone caps. my heart races and I feel very paniky with a headache. i had the same reaction to aygestin at the start of my IVF cycle. Ii was supposed to be on it for a week but my heart raced to much. I called my DR and she said I must deal with it as I need it. Has anyone else felt this . I was feeling fine until these pills started to kick in. I felt like the DR was a bit harsh about it.
