Possible pregnancy symptoms... I hope so!

I'm currently 4 days until af is due. The last few days have had a few strange symptoms.

Seem to have a constant dull/ burning/ achy/ cramping feeling low in my abdomen.

Random bouts of heartburn (I never get this).

Twinges in nipples but boobs aren't too sore. I usually get sore boobs before af.

But the cramping has really got me wondering now. It's been consistent for several days. It's a different kind of cramping and feels warm... So weird!

We had ovulation tracking done this month and I had my tubes flushed plus we BD a lot! So I'm really hoping this is it for us 🤞🍀
