My boyfriend is a butthole

I had a miscarriage about a month ago and had complications from it. I had a d and c and had more bleeding a week later. Things got better until now and I've been passing blood clots. I told my boyfriend and he said "Well it's not me this time" we're in an open relationship and we both had slept with other people quite recently. I opened the message and didn't respond and then he said "You saw me cum and I wasn't even close to you" which isn't true because he always does it on my back either way I know that I wouldn't be able to know whether I was pregnant or not right now because that was 4 days ago. Plus I didn't have sex anytime around the time that I was ovulating. So this is what I sent him "I never said that I was pregnant. I wasn't ovulating when I was at your house or even when I had sex with those other guys. I'm actually in a lot of pain right now and I was on my way to go see the doctor."
