Help!!!

I could really use some advice!! So I’m 2 days away from expected period and I keep getting super super faint positive you almost can’t tell they are there and they have stayed that way for three days. I have been having all the symptoms I had with my first 2 I know my body pretty well and know what happens when I get pregnant and how I feel. But with my second I was able to get a test 3 days before missed period. With her I did mess up and I tested to early turns out my cycle was going 42 days and I didn’t know. I’m only 9 months PP with her so I’m still kinda confused on my cycles. Is it possible that I could have already ovulated and my cycle is longer this month then I’m realizing?? I thought it was going 34 days but I could be wrong and it could be going back to 42 days. Sorry for the long post I’m just trying to figure out what is going on! Thanks for any advice or help!
