HELP PLEASE

It has now been 54 days since my miscarriage. According to a couple certified clinical studies on early miscarriages, i shouldve ovulated 29 days after, and my cycle would follow at 43 days after. 11 days ago on the 28th (day i was supposed to start my cycle again) my s/o and i had sex. usually when we do, his cum comes out almost immediately. this time was very weird and hasnt happened since but it took almost a full 8 hours for his cum to come out of me and the next day (29th) i spotted a tiny bit and nothing since. i have insomnia so i dont sleep so i always feel tired anyways, but ive been a little bloated and my nipples are very sore. could i even be pregant? when should i test? if i test and i am pregnant would i get a positive yet since its only been 11 days, 10 days since i spotted? i need all the help and advice i can get.. ttc rainbow baby🌈
