Lawd I'm late!

Shana
So.. I've been TTC for about a month and a half. Not long compared to a lot of you. I was on the Skyla for almost 2 years. So, I never had a period during that time. Before that I was on BC for about 10 years so, I was always on time with the packet. I was very irregular before BC, that's why I started BC. I am currently 14 day late on my period. Ive taken a pregnancy test and both are negative. I need some advice. Do y'all think it's because I may be prego (even tho test say negative) or it's my period getting all irregular again? Hoping for some serious baby dust for all of us!!
