Baby #2??

Hi all! I posted (so I thought but I don't think it worked) the other day. My boyfriend and I have been TTC for 8 months now and haven't had any luck. Last month I had a very irregular period, I bled for 13 days but it was spotty and dark and this month I am 10 days late.. I've been pretty spot on with my period starting on the day my tracker says but not this month. I took a test about a week ago and it was negative... This would be baby #2 and my first child I didn't find out I was pregnant until I was 32 weeks. With my first, ALL of my pregnancy tests I took at home came back negative and the only reason the dr found out was because of a blood test. Any thoughts or advice?
