Maybe leftover hcg or a new pregnancy?

idk if I am truly 11 dpo because I never got a positive opk but that’s what my Premom app estimates

Been waiting for a fully negative pregnancy test, after having a TFMR at 7w2d on 2/4 but I’m wondering if I am already pregnant again even though I did not get a positive opk my pregnancy test seems to be getting darker??

Day before yesterday I was like OK cool finally fully negative then I will ovulate again soon and it looks like my ovulation test are getting darker, but I wonder if they are responding to hCG that is actually increasing instead of decreasing

Do you think this would be due to ruine variation and being diluted or do you think it could actually be increasing? And i couldd be pregnant again alreadyy fingers crossed?

How possible or likely is it that I ovulated but didn’t actually catch my surge even though I’ve been using ovulation test almost every day and I know I am using them correctly
