Uti??

So i’m 18 and i started having sex a couple months ago.I’ve never been to gyno because i’m always busy and now that i’ve finally found some time this coronavirus thing came i am scared to go.I had uti a couple months ago and i was on antibiotics.After a week i was fine but since then when i go to the toilet i feel something itchy down there(sometimes) and my urine smells bad.I don’t know if that’s uti because when i had it i had terrible pain in my belly i couldn’t sleep.I am scared because i read that if i don’t cure this i may not be able to have kids.Should i be really worried?I can’t sleep because of that thought.I really think of going these days no matter of the coronavirus.What are your opinions ladies?

sorry if there are some mistakes i am not english
