What is happening to my body after missing just ONE pill?

[SuperNervousness]

So, I have been on birth control for about nine months. The first few months were bumpy: I was missing pills, forgetting them, and was being just plain lazy. However, the other half, I've gotten really good with them. I take them every night, on the dot, or within an hour or so than when I usually do.

A little bit over a month from now, my boyfriend and I had unprotected sex that led to him finishing inside. We've done it before, but always got a morning after pill. This time, we decided to rely on the pills I've been taking. The thought process was, why am I paying and taking them for us to just get plan b? So, we let things take its course.

A week later was supposed to be my period. But, here's the thing, I managed to miss a pill for the first time in months in that week. The day after that missed pill, my period started out of nowhere, with somewhere around a half week of pills to take. I finished out the week, but with a weird on and off period. I went my placebo week with an on and off period. It was light some days, heavy others. I've read up that implantation bleeding is light, like spotting. Most of the time it was similar to spotting, while there were a couple of times it was like my periods. I was scared that I was pregnant, so I took a test. Negative. At the end of the week of placebos, I took another. Negative. A week later: Negative. I let it go and let my anxiety go. I wrote it off that since there were times that it was so heavy, the egg was probably in there somewhere.

Fast forward to now. It is Monday, I start my pills on Wednesdays, and I usually start my period 2-3 days when I start the placebo pills. I am so anxious that I think I may be giving myself nausea and diarrhea, however, that is also a symptom of early signs of pregnancy. I'm supposed to get more pregnancy tests tomorrow, but I know those can also be wrong. I'm scared and I don't know what is happening to my body.

That was two weeks ago. Since then, I have taken three more pregnancy tests at home. All turned up negative. I still have a week and a half of my pills.

However, as of late, my nipples have been sore, along with yesterday, I had quite a bit milky discharge. I'm worried that was leukorrhea. I have had a couple of cramps, that feel like period cramps, but that could also all be in my head.

Do you guys think I should go get a blood pregnancy test? I'm just absolutely terrified of giving blood, so I think I've been pushing it off. That, or should I just wait until my next period?

What do you think is happening? Is the stress jacking up my hormone levels? Or is it possible from missing that one pill that I became pregnant and I'm already a month in?

Please help. I am so anxious I can't think of anything else, but thank you greatly for your time.

So, you'll have to take a test but I doubt you are pregnant.  Agree that taking plan B for mistakes that were occurring more frequent than once a year is not good.  That's not good in general because it messes up your body each and every time you take plan B.  It's a whopping dose of hormones and is meant for emergencies which is supposed to be rare.  So, try not to take Plan B.  You are on the pill which is effective if taken correctly.  Soooo, you missed a pill and started spotting (most likely spotting and not a period---  they are different.  A period happens after you ovulate while spotting occurs due to things like shift in hormones).  Then the symptoms you mention are also things that happen when hormones shift.  Which they probably did when you didn't take your pill and then took it again the next day.  

So, take a test to rule out pregnancy and then just keep on your pill schedule.  Do whatever you have to do to take that pill as directed!  

good luck
