Adivce?

So my boyfriend and I have been together for a year and 5 months. I have PCOS so my periods havent aren't always regular. I weighed myself for the first time in months. I was 196. I was shocked. i got my period last month. Normal 5 days. Im 6 days late this month. Should i test in another week? Ignore it? My boyfriend said if my period doesn't come in another week then we would but he knows how i get.. i hope for the best. get excited. then get let down.. just not sure. either way im happpy :)
