Mimi,
Think the jabs does affect temperature. I have started to record my temperature immediately after my menses came, 1 feb (failed IVF) and very weird, it just stays at 36.8. Only came down to 36.5 after my menses was over. Think normally, once menses come, temperuture shd drop drastically back to pre ovulation readings. So i think it's all the earlier hormone jabs which caused the temp fluctuations. In any case, i feelthat u are already in the midst of IVF, just ensure that u relax and have good diet, don't think too much into the temperature reading... ...
