Insulin during the day??

So I've been diet and exercise controlling my diabetes until 31 weeks when my fasting numbers went up...not a ton (95 to100 at the highest) so I started insulin before bed. Now I'm noticing that I can't always control my daytime numbers. Even if I have the right amount of carbs and take a walk after... my numbers have been 130-147 range. Will I need insulin during the day too? Anyone know how that works? 35 weeks now.. I'm so ready to be done with all the finger prick and needles.
