Possibly pregnant or maybe just in my head?

Sandra
I've had spotting almost every day since the day I should have gotten my period in April. I got of BC in February got a regular period in March and started tracking my periods but last month I got my period 3 days late and it was a spotty period and I still have been spotting since then I found out I may have a UTI yesterday and got put on antibiotics and got a pregnancy test done dr said it tooked to me negative but my bf and I have not been using condoms at all really could it just be too soon for a positive?? According to my period tracking we had sex about 2 on high fertility days
