Annoyed with myself!

So, I got rushed into hospital a couple of weeks ago, and had to have my first smear (OUCH) and they found some 'problems' and put me on medication. I was prescribed metronidazole, doxycyline, mefenamic acid, tranexamic acid and norethisterone. Well, I thought it was enough of a nightmare remembering to take them, and dealing with the nausea, vomiting, and generally being knocked out with all the side effects, I found out today that they severely decrease a woman's fertility! We've only been trying for a few days, so it shouldn't have done much damage, but I'm still annoyed with myself for not checking the leaflets when we decided to TTC.
