Help?

Natasha
I have pcos and have been taking minastrin fe birth control to help regulate. on the 3rd week of my pack I missed 2 pills in a row.. during those 2 days I missed my husband and I had intercourse. I did do the double up 2 pills and the next another 2. Of course I also had break through bleeding immediately and it is real painful and heavy like my periods. I'm suppose to get my period again in 6 days. My question is am I at risk of pregnancy? If so, does that mean I have to wait to find out after I stopped bleeding?
Update:
-Breasts grew like 2 times and are veiny, a little sore as well.
-Pelvic area is sore
-a little sharp pain on left side
-Nausea, faint, bad headaches
-constipation
I suppose to get my period starting tomorrow according to my birth control pack .. my bleeding is also a lot lighter now like it'sgoing  away. i'm just trying to pay attention to my body more till after i'm done with my birth control pack, and when the bleeding stops i'm going to pay close attention to the symptoms
