Urine infections

Ni

Not sure if I’m in the right chat room for this or not but recently my partner and I have started trying for a baby so we are having unprotected sex obviously as previously we used condoms.

In the past 6 weeks I’ve had 3 urine infections although the last time they gave me antibiotics for one but my test result showed no urine infection. My first urine infection was only noticed due to a sore back, god knows what is going on. It’s come on today suddenly again, uncomfortable stomach and sore to urinate which was same as last time but it only lasted a day but they gave me the antibiotics anyways last time and when I called out of hours today they’ve said something else must be going on and I’ve to wait to Monday 😩 I’m in serious discomfort and wondering what I can do to help even to be more comfortable ??
