side effects of clomid in 2ww?

Hello, everyone. I'm new here... I'm an older woman, 44, and i just started clomid this cycle, 50mg. I am fairly certain I ovulated because of the symptoms I am having. High temps, sore nips, tired, mild nausea. I know that the elevated progesterone will cause these symptoms so I guess my question is, can clomid cause elevated progesterone levels in the absence of pregnancy?

Thank you for any info you can share...and good luck to everyone. Also, are there any other "oldies" on this board?? I could use the company!!
