Can i be pregnant?

Is it possible to be pregnant even if ive had no symptoms? This is the first time i haven had PMS mood swings.. I spotted 5-6 dpo and i havent spotted again even after sex havent seen any spotting.. I usually start spotting 5 days before AF and this time i haven seen any spotting other than that pinkish spotting i saw 5dpo.. My boobs are veeyy huge and sore.. But other than that i havent felt any other symptoms.. I had unprotected sex 2 days after last day i saw EWCM.. Can i still have chance of being pregnant? Should i test or wait to AF.. Glow tells me AF dues int 2 days but other app (ovia) tells me AF due in 4 days..
