Hello, at the 8th of September I began taking the Loestrin Birth Control pill at the start of my period. 4 days in, me and my boyfriend had protected sex and the condom broke. Right after it broke, we stopped and did not try again. Last Tuesday, I was a bit worried and went out and bought a pregnancy test and it read negative. I am on my first brown pill from my pack and I noticed spot bleeding and then it stopped. My period is due Wednesday, the day I started my pills. I have not missed a single pill since I have started. Should I be worried or if not , should I be worried if I don't see it by Wednesday

At this point, I wouldn't worry yet. Wait and see if you actually miss your period or not. If you do, then take another test. They're usually not accurate until around the time that your period is due, and even then sometimes it's too soon.
Sometimes it takes awhile for your body to adjust, that may be the reason for the spotting. And even if you miss your period, try not to stress because stress can also delay your period. Do your best to relax.
