12dpo and af due on Saturday

I'm 12dpo, I use several different apps to track my cycle and some said I should have started af on the 5th, 7th, and 9th. Now my periods have become a bit irregular over the past 3-4 months but I did an opk last month and while we're just not actively trying we do and did have lots of sex around that time even before I was off my last period (sorry tmi) but I've been feeling different this cycle. I normally get pms symptoms before af comes but this time they came earlier and I have been getting headaches, dizziness and very vivid dreams. I also had a fluttering sensation at like 6dpo and I know it wasn't gas. I don't like to read into anything but I'm kinda hoping I did conceive as we both want a baby together and like I said we're not "actively trying " but we're not trying to prevent it either. If it happens it happens so baby dust my way and to all you fellow ladies who are trying to conceive. I took a test a few days ago but was a BFN. Too soon obviously so ladies who are waiting with me post your comments stories or whatever. Let's hope we get pregnant this cycle. 🤗😍😘
