Hi Linda and welcome to BB & this thread. I have just completed my sixth & last round of clomid and are currently in the tww. I have 'heavy' bbies - in the past my nipples (sorry of tmi) would be sore, but this time they are 'heavy', no nausea though. I did get side effects on Clomid such as insomnia, hot flushes but no nausea. I took my Clomid in the evening & this was suppose to lessen symptoms. I know nausea can be a side effect from Clomid but can indicate early pg. I am not sure when you O, so perhaps it is too early to test for pg? I did a test yesterday & it was neg but I am still hopeful & will re-test tomorrow when AF is due. Best of luck to you
