Tell me I shouldn't be discouraged yet

Kerry • Mommy of 2 special little boys!💙💙

Ok ladies so I actively tried to get pregnant this month and my period is due somewhere between July 21st and 24th. I'm having so many symptoms but I was positive I had a uti so I went to urgent care and explained my situation and that it be too early to test for pregnancy, but if I had a uti I needed something safe. I'm only like 3-5 dpo and I dk why but I guess I was hoping they tell me my pregnant test was positive but hey said it was negative and so was the uti. I'm still having back pain and some discharge. The doctor told me to retest next week for pregnancy and I could just be too early. I'm hoping I'm not out this month and it really is too early. Anyone have an experiences like this and any words of encouragement are welcomed!
