I'm a little bit confused and I'm hoping someone can help me. My Premom app says I ovulated Sunday and my Ovia app says I ovulated Friday. I have been diligent with my OPKs and got a really strong peak (1.67) on Saturday night. Tested again yesterday and got a high (0.87). When would I have likely ovulated? We DTD on Saturday and Sunday night and I'm hoping that's enough, but I'm a bit worried as Ovia said I was due to ovulate Friday and we didn't DTD then. Do I just go by the OPK peak and assume I ovulated Saturday/Sunday? Thank you in advance.
