Uti's are so painful and annoying my suggestion from someone who had them every two weeks for 2 years when i was in my late teens. My preventors were, cranberry juice twice daily, lots of water, after sex go to toilet (i know you are TTC but maybe wait for 10-15 mins then go to loo) make sure you completely finish weeing after sex and drink heaps of water to flush yourself out. Good luck hope this helps.
