could I be pregnant

Since I noticed milk would come out when my fiancé and I would mess around , but I haven't had this problem before last time I  breast fed was 3 years ago . We don't use protection just the P&P ( pullout and pray that I don't get pregnant) but he has ejaculated directly on my vagina while my legs where still spread.  Nervously waiting on my next period if it should come 😱I've noticed my sex drive is extremely low which is crazy because it's usually incredibly high . My boobs are some what sore/ tingly but it's still too early for me to take a pregnancy test so theses next few weeks are definitely going to have me going crazy.
