Don't want to get my hopes up!

So me and my boyfriend have been together for almost 2 years and we really aren't trying to conceive. It's something we wanted to wait on until we are married and have everything. But recently I have been EXTREMELY emotional. I broke down at work the other day, and I have been moody. (Let me just say that currently, I am on the implanon for birth control. I got it maybe two months ago for the second time.) last time I was on the implanting I had a period almost every month, it was very irregular but I always had one. This time, I haven't had a period at all, & my boobs have been very sensitive & I'm kindof worried that I may be pregnant. This would be a blessing, & I would be excited.. So I just want to get some feedback on what yall think? Thanks!
