came in during ovulation, alternatives??

I don’t want to be shamed and I know the solution is to get on birth control in the future, wear protection and to take a plan b right now but I need some insight. I have been having unprotected sex with my male partner for a few months now, and I cycle track regularly, but my cycle now has been thrown off (it came on a week late last time) so I don’t know if I’m actually ovulating right now or not, <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I am, but he came in me today due to miscommunication on his part and I don’t want to take a plan b because I don’t like all of the hormones, the skin side effects and how it’s made me feel in the past but I do NOT want kids right now. I’m wondering if any of you have any alternatives or have been in my shoes before? This just happened and I’m debating on if I should wait it out or get contraception.
