So this is day 5 on placebo pills and still no signs of my period...

E
Sitting here on lunch at work and stressing out. I usually get my period on day 4, sometimes day 5 on my placebo pills. Still nothing. I've been taking birth control for a year and a half and I take it religiously. Never missed a pill. Gave up grapefruits and drinking. I do take metformin but my doctor told me I will be fine because of how good I am with taking my birth control. 
I'm in a LDR with my boyfriend and you know what happens when I go visit him. 
I was having really weird cramping, didn't feel like period cramps. But I've had those in November too. I feel fine.  But what if I end up being one of those "I didn't know I was pregnant" people. Ugh. 
I always stress out after I come back from vacation. I always WANT to get my period because then I'm not stressed. 
I have until the end of today to get my period... I should probably just take a test. 
Why do I do this to myself. I just need to get my tubes tied already. :/
***Edit: my period exploded out of me. I'm safe.
