Can you ladies help me out?

So, I’m posting this here because I don’t know where else to post it. In January I was on birth control til pretty much the end of the month. I was on the “sugar pills” at the end of the pack the 18th-24th. Then I stopped, and didn’t start another pack. Then I started another “period” on the 30th up until the 2nd of February. So I’m counting that as my “first day of my last period”. Well, according to glow, I’d be 13 dpo today and I took 2 pregnancy tests and see faint lines on both. Both were looked at within the time frame. But when I do a calculation of a due date it says I’m only 2 weeks and 5 days and everyone says that’s impossible and too early... do you ladies know what’s going on? Should I be counting my other period???
