Thanks Jay-Bee and Morgan, all went really well in my opinion.
The procedure itself couldn't have taken more than 2 mins and it felt just about the same as having a pap smear done. And my FS is really great so I wasn't nervous at all. He told me to ensure I have a full bladder since it will press on the uterus and force it to be more vertical, which makes it a lot easier to get the catheter to where it has to go. And the doctor in the laboratory where hubby's sample was being prepared, showed us through a microscope what his little swimmers look like, so that was really interesting.
Have to take progesterone pessaries (

like a suppository but inserted vaginally) for the duration of the tww. Bit of a messy business, but not too bad. Beta test is due on 21 April and I promised myself to wait for the results and not use HPTs.
@AnzelMama, well done for seeing the positive side of not being successful yet. As I always say, its difficult now to see why things turn out the way it does, but over time it becomes clear way we should wait for God's timing.
@Morgan, sounds like you got some good advice wrt being gluten intolerant etc. I still believe there are so many things the influence our health that we're not aware of. Good luck with sticking to your new diet. I hope it works well for you.
@Cynthia, have you tested at all? Couldn't figure out if you know its BFN because the meds didn't work, or if its possibly BFP but you haven't done any tests.
@Betti, glad to see that all is still going well with you and your little one.
