Mum2One - Everyone is different of course, but I always find the symptoms start after I have finished the Clomid and the whole month is an emotional rollercoaster. I had the general SE once finished the Clomid (hot flushes was my main SE), but then everything else during the cycle seems to be "bigger" than usual. More emotional, PMS is more full on, boobs can be sorer (I never really had sore boobs before, but I do on Clomid), I even felt nautious around ovulation the first cycle and I am the same this time (4th cycle). I have also found that I am worse each month, but others have said that their first month was the worst. I am sure that my husband would agree though, I am definitely getting worse as I go along!! Pretty much any PMS/Pregnancy/Ovulation SE that you can think of, you will probably feel. Partly because you want to think that you are Ovulating/Pregnant and partly because the hormones are just pumping harder than usual because of the Clomid.
