Advice please

Hi so last month january 1st i had miscarried i was 7/8ish weeks, and me and my partner had sex a couple times twice coming off my period since it was so little blood we didn’t really care, and it wasn’t even as in a ttc way, but then we had done the baby dance again a couple days before i started ovulating, and i’m now 5 days late. my boobs have continuously been big, i’ve realized i have been gaining weight, my boobs aren’t super sore like last time i didn’t have any small implantation bleeding like like last time my moods are different this time. so i’m wondering if im 5 days late because my body is skipping a cycle or if i’m pregnant, im planning on testing in two days because that’s when i tested the last time, but until then i would like some help on my situation.

i also think it’s important to note that last baby was unviable and was unfortunately gonna miscarry anyways.
