Is it okay to go moderate hiking??

Courtney
This morning early we are headed up a Mountain to hike 4,000 feet in elevation as well as some trails may be moderate to strenuous. I also have a safe antibiotic for my UTI. I am 4 weeks along and worried about this 7 mile hike? Should I go?  Nervous nelly and probably a really stupid question. Thanks Glow Community!
