5-8 days late should i start testing?

So basically im on cd 38, between 5 and 8 days late depending if you look at my average cycle length of 30 days or my longest cycle length of 33 days( that happened 2 out of 11 cycles. My lutuel phase on average is 11 days the shortest 6 days (onee time) and longest 14 days ( 1 time). I chart my bbt but because of a fever and i had 2 drops 6 days apart im unsure exactly the day i ovulated either 16 days ago or 21 days ago. As for symptoms ive had sore boobs for about 5 days today and 2 other days this week ive felt a bit nauseas today being most noticable. Definitley have alot of cm and urinating alot( noticed a whole role was gone in a couple hours and i was the only one home). The only other thing i noticed is very loud and gurgling intestines and stomach. On top of it these symptoms are all fairly knew with the oldest sympom being cramps starting about 11 days ago and being on and off. The first time i noticed cramps was actually about a day after the second drop when i had a fever for 4 days. Besides these little things ive had no other symptoms.

Im not stressed at all im actually the most relaxed ive been in a long time as im on vacation from college at the monent and im done in 4 months, although i have been sick as i said before and im almost completely recovered now.

So what i would like to know is if i should test yet or not because i dont want to concern my boyfriend unless i actually have to and im at his house so im sure he is bound to see it and ask. I also have a pap test tommorow and im unsure if i should reschedule or not.
