Desperately Needing Serious Advice

My long-time boyfriend and I have sex very often, at least every day or so. We’ve always used condoms and since July I’ve been on birth control, which has lined up my periods very well and now they always start in the middle of the month.

Just as a bit of backstory for later, I’m going through a really hard time with family, school, and some other major life stuff, so I’ve been pretty damn stressed out.

On October 5, I stayed the night at his house and forgot my pills. So instead of taking them at 7 am like usual, I took them at 11 am. We made sure to be careful for the next week. Then on October 12, I stayed over with him at a friends house. I took the pill on time, and then about an hour later we had sex in a steam shower, but since we didn’t have a condom, we just finished with anal & all was well.

Now it’s October 16th and my period still has not come. My thoughts are it’s either 1.) late from so much stress 2.) late because I took that pill on the 5th late, which I find unlikely, or 3.) I could be pregnant from his precum in the shower.

If it’s 1 or 2, I’m alright with it. But if it’s 3, and I am pregnant, I think it’s wayyyyyy too early to tell. But just as a precaution I did my research on how to make a period come early. I’ve been taking insane amounts of Vitamin C, eaten so much pineapple I think I’ll explode, and excessively exercised the last two days. Still no period, but I’m having a lot of white discharge. The internet says that’s a sign of a low fertility part of the month. Is that good or bad? Should I be worried? When should I take a test if my period still doesn’t come? Help would be greatly appreciated 👍🏾
