Anyone else?

The first day of my last period was December 30th, 2017 through the 2nd. My ovulation was kind of weird the month of January but we did the baby dance just to be safe. My expected start for my period was February 7th...it's now 44 days since my last period...I've taken 4 test and BFN :/ We had a miscarriage back in August before the miscarriage I had a ton of symptoms and I knew I was pregnant but could never get a positive home test so I went and got a blood test and that's when I got the positive! This time around I'm having very little symptoms (missed period, food cravings, bloating, headaches, bloody nose, certain smells make me naseus) I was sick in January so I keep saying that's why my period is late but part of me wonders if I should go get a blood test. Does anyone else have problems with home pregnancy test?
