Hormones

Idk if it's just my hormones or what but I'm about 6 days late on my period so I tested and I'm not pregnant. My SO  and I are buying our first house together I work 3 jobs from 5:30am to 9:00pm and he works 1 job 7:00am to 5:30pm and I'm getting anxious the closer it gets to closing but Lately my sex drive has completely deplinished from 4-5 times a week to once maybe 0 through the whole week and not only that but I have become really irritable towards my SO whenever I just see him like the slightest thing pisses me off. Then on the other hand I get so needy for him. I know it sounds like I'm bipolar but this just recently started maybe 2 months ago when my periods started coming late and when we started looking for the house. Anyways I guess what I'm tryin to ask is, has this ever happened to anyone else?
