Advice Please?

I'm 19 turning 20 and my husband and I have been trying to concieve for 2 years now. This is going to be long I'm sorry but please bear with me because any advice is much appreciated. After many months on end of anxiously being excited and getting our hopes up time and time again only to be heartbroken every time we finally gave up. As heartbreaking and devastating as it was to stop buying the tests and the ovulation strips and the preconception items we had to for our sanity. Now about 3 months after giving up I realized my period is late. Only by a day but late. Since November my period has always shown up between the 15th and the 18th. The last 2 months it was the 16th and the 17th for the start dates. Typically I get some light cramping that gets worse and the bleeding starts within hours. However the Glo calender says I'm not due for my period until the 23rd. My breasts the last 4 or 5 days have been extremely heavy and swollen/tender to the touch. Yesterday and today I have had weird cravings that I dont typically crave before my period starts and have had no sign of the usual cramping. I only have digital pregnancy tests left over since we stopped trying and a handful of OPKs. I nervously used an opk, which when we were trying never really showed a line except on peak days, and there was a solid second line on the opk. I have heard that OPKs also pick up on HCG, I'm really anxious and dont know if I can handle staring blankly at a bold "Not Pregnant" again with the digital test, and I wont be able to make a doctors appointment for at least 2 months (Unless I confirm a pregnancy and swap physicians). Should I just suck it up and take the digital? Should I tell my husband, who has countlessly pointed out my mood swings and hormones? Is it too early for a digital? Am I judt crazy with these symptoms? Is it too early for these symptoms??? Thank you in advance for any help.
