Pregnant after loss

TW: miscarriage

My husband and I lost our first baby October 17 at 6w6d. We were absolutely devastated, but I decided I wanted to try again asap. My doctor said we could have sex 2 weeks after the mc and said we could try again after my period, if I was ready.

I decided to randomly take an opk two weeks after and it was pretty dark, so I said f it and we BD that weekend. Got the positive/peak opk 11/2 and just tested positive at what I presume is 10dpo!!! I’m anxious as all get out, but did allow myself to be excited. I need to call the doctor, but I’m nervous they’re going to be shitty because I didn’t wait for my period to come 😅 also how the hell do I figure out how far along I am?! The mc bleeding stopped by 10/22. I know they’ll do an early scan to try and determine gestational age, but I’m just curious what others’ experience was with this!

Really praying this baby sticks and makes it earth side. 🤞🏼🌈

ETA: my beta went from 72 to 153!!!!! Grow baby, grow!!!!
