I need help!!

So I’m late on my period , it is May 16th and my last period was Feb 24th but I have gotten blood work done almost 2 weeks ago for pregnancy and it came back negative, and it’s still not here. I was gonna make a doctors appointment but they have told me if I miss more than 3months to come in, but I’m really considered. But I also just went threw a really bad UTI And yeast infection about 2-3 weeks ago.

The hospital messed my UTI antibiotics up and put me on 3 different ones because they couldn’t find the right ones, and then that caused by yeast infection which ate my skin alive so was on meds for that too and now this , I’m going crazy I need opinions!!
