Husband maybe cheating

Hey maybe out of pregnancy topic but i was going thru my husband phone he always has it locked and i finally figured his password i was going threw his pictures and i saw that he had alot of his dick pics on there ever since i started going out with him he would always say that he doesnt like taking pictures like that this and that i saw also a P pic and tbh i dont know if is mine or someone else but now thinking about it it doesnt look nothing like mine i usally send my husband nudes before pregnancy but still i dont think that P pic is mine idk what to think i went thru his mssg didnt find anything cause i was in a hurry but idk im just so confused why would he take dick pics he took some in the car why would he take them there unless someone asked for them right ? Im am 5 weeks away from my due date my last pregnancy he was talking to other girls as well so idk im just kinda sad and over it and what hurts the most he always does it while i am pregnant
