Anxious about a recent intercourse

Hello SafeSexPH! So me and my girlfriend had unprotected sex last Monday (May 8) and Wednesday (May 10). So far, wala naman daw siyang nararamdamang kakaiba at ayos lang siya but anyway, here are some more info that could be useful:

  • Monday medyo matagal kami. Pulled out when I was feeling more pleasured, not climax.

  • Wednesday saglit lang. Pulled out ulit when I was feeling more pleasured and finished her instead. So we're both guessing na there was probably precum on both days where we engaged on an intercourse.

  • Regular period. Ang huli niyang start ay April 16, which ended on April 23.

  • I don't know much about the ovulation period, pero she told me na it happened during that period (ovulation).

Since we did it on her ovulating period, we're very afraid that it would put her in a great risk of pregnancy. How at risk are we? Is there anything that we can possibly do for now, or just wait it out and take a PT? I apologize in advance for any shortcomings in terms of being educated about safe sex (but I'm trying my best to learn since I'm new to this) and also thanks in advance if anyone responds!

Oh and btw, I told her to cop some Trust pills earlier (mga 3:00PM) with an attempt to do the Yuzpe method pero pinigil ko muna at hindi ako sigurado kung necessary ba siyang gawin lalo na't iilang araw na rin ang nakalipas (although may info from planbillmanila.com na even after 5 days, may 25% efficacy rate pa rin ang ECPS. Although I'm not sure kung same lang ba siya.)
