Bladder issues

I have for the past 2 weeks been feeling like I have a bladder infection coming on but it's not bad that I have to go to the doctor if that makes sense? I have also avoided the doc because I don't want to take antibiotics as my husband and I are trying so I have been taking natural remedies but this is truly an odd feeling as I write this, it's not a burning but a weird feeling and need to wee constantly, I am going to the same gynecologist who delivered my baby boy tomorrow and I think I will be so disheartened if it turns out to be a bladder infection for the 100th time this year!!! 😱 we have been trying for 3 months and just have this sinking feeling something might be wrong with me. I'm now in my fertile window and suppose to be trying but how can I, when I feel like this :( I suppose I will get my answer tomorrow if something is wrong but I'm so frustrated as my whole life I have had bladder problems, been tested but all seems to be ok.. I know the feeling of being pregnant and this ain't it. Anyone ever experienced this and what did they do besides seek medical advice?
