Nora Be. Pregnancy?

I should start my period in 5 days. Last month I did not get a period, month before that I was a week late, and the month before that month I was also a week late. I usually take my BC at around 8/9 PM But this month I have made a few mistakes. One night I almost forgot and took it at 10/10:30. And on July 6 I threw up after I took all my pills (including my birth control) but I’m not sure how long after I threw up after taking my pills. I’ve been sexually active since the 8th of July. Around the 16th my right abdomen start to swell up and I started cramping very light like you know how it feels right when you begin to cramp before they get bad? It felt like that. I also had some discharge it was white but it wasn’t gooey and it was on my underwear. I have been moody like mood swings but that could be from a lot of things my nipples have felt sensitive that could be from my bra possibly and I’ve been gassy. I’ve been on Nora be for about a year maybe a year and a half at most 2 years. Is there a chance I fucked up?maybe I’m experiencing PMS I’m not sure because I haven’t gotten my period since May (to clarify I haven’t been sexually active until this month) because I’ve been on BC for so long is there a chance I am still protected?
