Someone please help! I don’t know when I conceived

Hi everyone!

I just got my BFP and I’m excited, scared, and confused! My husband and I started TTC a few months ago and after 2 months of not getting pregnant we decided to stop worrying about it so much since it was starting to consume me. After I got my period on August 14th I stopped worrying about my ovulation day and just enjoyed the rest of summer. However, here’s where things get interesting! I was changing yesterday (Sept. 5th) and felt/looked SO bloated. I decided to take a pregnancy test and it was positive! I took 3 more tests and two again this morning and they are all positive! I’m not talking about faint lines either, I mean dark, obvious positive test results.

I am so confused since according to the app, yesterday was only 8DPO (predicted ovulation day: August 28th). My periods have always been super regular. When I first started TTC I used ovulation sticks and the app was right about when I ovulated. However, this cycle I didn’t use them.

I’m so confused since everything I’ve read tells me I shouldn’t have got a dark positive this early.

Thanks in advance!
