Hi Bun

I am now on my 5th round of Clomid.
After coming off the pill my cycles were very erratic and almost non existant. I even had 1 cycle last for 100 days. Tests showed that i was not ovualting so the doctor put me on 50mg of Clomid. This didnt make me ovulate so i then went on 100mg, again it didnt work and then we tried 150mg, no ovualtion again.
I then had a laparascopy/hysterascopy which showed i have mild endometriosis. After this procedure we actually fell pregnant without Clomid, my FS said he has seen that a lot, he believes i may have had a blockage somewhere and the flushing of dye through my tubes during the procedure cleared this up. Unfortunately the pregnancy didnt last.
My cycles were still erratic after the miscarriage so he put me on Clomid again, this time 100mg. It actually worked this time, i ovulated which was great news, unfortunately we didnt fall pregnant that month. So i took another round of 100mg of Clomid this month and am still in my 2 week wait to see how we went this cylce. Fingers crossed.
During the first 3 rounds of Clomid i felt quite a few side effects, headahces, a bit moody, emotional and feeling a bit sick in the tummy. Nothing i couldnt handle though.
This last 2 rounds however i havent really had any side effects which has been great. I have been making sure i take the tablets when with food, i am not sure if this is why it is different than the first 3 rounds though.
I have ovulated in the last 2 rounds so perhaps the reason Clomid didnt work for me to begin with was due to the blockage i may have had.
My overall experience with Clomid is not too bad, i take it from days 5-9. I am glad when the 5 days i take it are over as i dont quite feel myself but i am happy to do it as many times as it takes to get the end result we are after.
With the erratic cycles i had been having i am just pleased that finally i am ovualting and my body seems to be working the way it should, although we havent had the positive pregnancy result again yet i am feeling much better with regular cycles.

Good luck with your round of Clomid, i found these forums very helpful when reading about other peoples experiences.
Here's hoping positive news is just around the corner for you, good luck.
