Possible or no? Need opinions please!

Chloe • Ttc #1 and diagnosed with PCOS

So my cycles have been ALL over the place and I don’t even know what was considered my period because of all the spotting I was having. My gynecologist made me get on birth control because of it, despite me ttc. I started on the 8th but I at some point missed a pill and I didn’t realize it till quite a few days later when I noticed I was on the wrong day. I only had sex on the 13th but is it possible to conceive? In the past few days I’ve had sore breast, nausea, and fatigue. I also had two days of spotting after a week of no bleeding and now I have no more. But I know these can also be symptoms from birth control 😢
