Thanks for thinking of me! I'm kinda feeling like crap

My stomach has been a bit upset the last few days. Not nauseous, but heart-burny. I had heart-burn really badly my whole pregnancy with Ethan. My temp dipped a little bit today, but I got up extra early for work, so I'm hoping that's it. I'm trying not to get excited, but its kinda hard when I'm feeling this yucky. I'm going to try to hold out until Monday to see if my temp is still up; I'll be 12 DPO on Monday. I'm flying to Michigan on Thursday to visit my BF from college, so hoping to know before I head out there.
I'll be super-excited if I get a BFP, but really nervous too. I lost 4 pregnancies before Ethan, so trying to emotionally prepare myself. I will say, my cycles are REALLY different since the baby. They used to be super-short, like 20-21 days & I would have AF for a solid 10 of those days. My cycles have been much more "text-book" since then. Hopefully that's a good sign!!
