Could I be pregnant?

[Jojofruit]

I have PCOS so becoming pregnant was difficult as my period was irregular. After my both pregnancies, last one being 3 years ago, I have been plotting my cycle on this My Cycle calendar and it's been on point for the most part. Probably would come sometimes before or two three days after. I would know it's coming because couple days before the date I would be miserable in pain. Back, abdomen, legs everything hurting. So I did go through that and should have expected my period on October 5th. I had intercourse on the 6th but my husband pulled out. So.....is it at all possible that I may be pregnant? All my PMS has subsided and this is the longest I have waited for it to come.
