Pregnant or nah?

Mackenzie

So I’m officially 26 days late on my period, I’ve taken about 5 home pregnancy tests at various points past ovulation and at different times of the day, all negative but I’ve been super tired (could be because I work two jobs) and have bad headaches lately (could be because of lack of sleep) nausea and feeling hot and uncomfortable... I’ve also had some cramping like I’m gonna start my period but never do... should I go get a blood test done or are my periods just being even more irregular than usual due to having frequent unprotected sexual. We have been trying for over 6 months and getting all the negative tests makes me not even want to take them anymore...
