question about cycle and pregnancy possibility

Maria

So here's a question my husband and I had sex on these days mark expect on the 19th he didn't finish inside but it was still unprotected this whole time. I think this app as my ovulation dates a bit off. because I saw egg white since a couple of days back and I think I ovulated today because my body felt like a high fever and pain on my left side. it lasted for a while and then it my body tempture went down. That's why I say I know I ovulated. anyways is there a possible chance of pregnancy even if on the 19th he didn't finish inside.? I have to apps and one I've used since I was 18 I'm 22 now. He has his hopes for baby but I had a miscarriage about little over 1 year ago or so and it was unexpected that I didn't know I was pregnant it wouldn't show in test or blood until the ER said I had the miscarriage. so I'm kinda of eh about having the whole pregnancy.
