Needing thoughts and opinions!

To start, I’ve been on BC for at 6+ or so. I missed my first two pills of a new pack (Feb. 4-5th). I had unprotected sex on the 4th and then remembered to take my pill on the 6th. So then, I took the pills from the 4th and 5th only. And on the 7th I took the pills for the 6th and 7th.

I had unprotected sex also on 7, 10, 11, 12th. But I was back on track with my BC until the 11th. I missed those pills (new schedule, new job, has me all messed up). So my fiancé and I just decided to see what happens and not take the pill.

I had some bleeding, but only lasted about 4 days. It was kind of heavy and then lightened up. My period isn’t due until the 27th, and I’ve been experiencing some various symptoms. (Swelling of breasts, extreme tenderness in breasts, fatigue, lightly nauseated and some light cramping) My last period was on January 30th. So, I was curious to know if I could be pregnant?

Oh and my fertile window was between 7-13th and my ovulation day was marked to be on the 12th based on the calendar. I read that the bleeding could have been withdrawal bleeding and I still could be pregnant....🤔
