Advice needed... ladies.. help me help you help me lol

hello lovely ladies. We're very new to the app but hubby and I have been TTC for months now. This is my baby #2 but #1 with my husband. So I'm trying to make the hubby experience all the awesomeness that comes from having a baby too not just a step child. So..let's start by saying.. It was hard coming off of the NUVA...too many hormones..but we finally got my AF regulated...until this month. AF was suppose to get here on the 27 but it started on the 25th on and off brown discharge and no real life blood. I'm getting concerned. specially since I have a tendency to have little to no HCG levels in urine with my first baby I didn't know until I was 2 months. Anyone gone through the same. I wish I could just pee on the stick and voila...but noooo... it all has to be complicated. thank you in advance. xoxo TCHAU!
