Did he cheat? Please help.

so this past Friday night my boyfriend and I went out drinking. We were really drunk and he mentioned getting a stripper to come to our house but we ended up staying out later than expected. He did coke that evening as well so e was able to stay up a lot later than me. We went back to our house with a few friends and I went to bed at 4:00 am. He woke me up at 7:00 am saying he was going to his friends house 10 minutes away to get more coke because he hadn't slept all night and needed more because he was signing a contract in the morning. He also again mentioned getting a stripper later which I liked the idea of. Let me put out there that I am open to another woman joining us and we have been looking to have a threesome with another woman. At 8:30 he called me telling me to hold on for like 20 minutes and then come pick him up and I checked his call log and saw at 9:00 he called and spoke to his client. At 9:30 his friend called me and said he took his car and must've just left but his phone was off and he didn't know where he was. And 9:45 I got a text saying he was ok and had gone to get a charger and to do some more coke with another friend who was there. I called the other friend and he confirmed my boyfriend called to say he was coming back. I'm sketched because when I called my boyfriend after he texted me he said I'm with a client and hung up. I picked him up at 10:15. I went through his call and message log online and saw he had texted a number which turned out to be an escort and called another one that turned out to be and escort. I called the one he texted and told her I wasn't mad and just wanted to know what he texted her for. She told me he told her he was looking for a show for his girlfriend but that she didn't do couples. I was relieved but when we got to the house I wanted to fool around and he didn't want to. I asked to smell his dick and he let me.. It had a smell like pee to it and I told him it smelled bad. He said it was because he had so much hair and hadn't shaved in awhile so he started shaving it. It didn't smell like a vagina or a condom and when I looked in the underwear there was a small stain like maybe a pee stain? So maybe it was pee drip? It just weirded me out that he acted weird but normally he can't have sex while he's coked out until it starts to wear off. He ended up having sex with me a few hours later. He also told me he called and texted these women. Does this story add up or do you think he cheated? I can't take this. I'm 9 weeks pregnant and having a heart attack. I just don't know. From the looks of his call log the only amount of time that he didn't text or call anyone was from 9:00 to 9:30 also the other girl I called said she has to have a morning appt booked a day in advance.
