UTI after ovulation whilst ttc

Dominique
I ovulated Friday 8th - my partner and I have been bedding everyday over the fertile period and I think it's been too much. Last night spent the evening at urgent care for antibiotics because I had blood in my urine diagnosed as UTI. 
I was wondering if anyone has experienced this and any tips in preventing it from reoccurring.
I shower 10 mins after sex usually if not straight away. Is it due to the sex being to hard or? Will it affect my chances of conceiving this month?
Any advice would be very much appreciated.
