Hello! 

I'm 19 and my period is late by 17 days now. I am on birth control and take it at 9 o'clock sharp every morning. I was never really adiment about keeping track of my period until I became sexually active with my boyfriend soon to be fiancé. However once that had finally happened I kept track of it using my period tracker which I normaly would have between 25-28 days between periods. The past few months however have been different, 2 months ago I missed my period and only had a dark brown spotting that was old blood mixed with the regular clear discharge that usually signals your period is on its way. Month before that I had about 32 days between my period. Last month was 33 days between my period and this month was suppose to be 35 days between my periods. The days between my periods have been getting longer and this month I have yet to even have my period although I had the clear discharge I usually get before my period but that went away after about a week. I feel like my boobs have gotten bigger I was a 38C and they don't fit as well in my bra as before. I haven't experienced any other of the regular symptoms that I've heard and read about that are common with pregnancy and I took a pregnant test about 2 weeks ago and it came up as negative. I'm going to take another test as soon as I get my pay check as well to double check. My sense of taste has been a little weird with only two types of food turkey bacon and this ham steak that I never really cared for in the first place so it may just be my brain playing tricks on me since I've been worried about not Getting my period yet. My allergies have been pretty bad with pollen the past week and I am also on vyvance for my adhd but didn't take those pills for a few days and then started taking them again. Any help on what could be wrong or a suggestion about it would be great. I'll probably be going to my doctor soon if my period still doesn't come even after I take te other pregnancy tests if they aren't positive. I apologize for any spelling errors my phone is not taking kindly to the website and is making the page scroll from top to bottom as I type and is becoming annoying. Thank you!
