Missed Pills/Spotting/Sex

So when I started my pack of birth control this month, I actually missed the first two days. Then I took the next four days regularly. After that I missed another two days. And then I took the next two after that. So I’m about a week and a half into my pack and I’ve taken 6 pills and missed four.

I’m usually much better at taking my pills normally, but my work schedule got very hectic recently and has thrown me off a bit. I didn’t realize that I had missed so many days.

Yesterday I was spotting. I had sex with my husband and this app says that my chances of getting pregnant are high. (But is that accurate for people who are on birth control?)

I’m trying to figure out if that spotting was withdrawal bleeding or ovulation bleeding.

We aren’t trying to get pregnant, but we want to start trying within the next year or so. I don’t want to jump to any conclusions and get ahead of myself about possibly getting pregnant if it’s not likely.

So, what do you guys think?
