I've got to wait til the first day of my next period and then ring up to book an appointment as you can't ttc during the cycle you have the HSG. I went & bought some condoms yesteday in preparation - it felt very odd!!
You can still TTC when you have your HSG. Unless you mean you can't have sex before you have it. Have your period, wait a couple of days, have HSG. After though is fine

There is evidence to suggest you can be more fertile!
Ah - the information they gave me at the hospital says you musn't have unprotected sex at all that cycle. It says " It is unsafe to try for a pregnancy in the menstrual cycle in which this test is performed; please do not have any unprotected sexual intercourse in that cycle"
Reba - it does also say " For women with very irregular periods the test can be performed at any time after a negative pregnancy test." You have to do a test the day before the HSG.
Emmy - don't give up - we'll get there! I've thoroughly enjoyed my 4 days off - really nice bread, mash, chocolate, cheese ice cream etc etc but I'm trying to keep to it this week!
Love and baby dust to the rest of you (just love to our baby lurkers!!)
