First timer here. Little confused. This is SOO long. Sorry

So I just got married and got back from our honeymoon this Saturday 10/7. I suspected that I was ovulating on the 3rd from CM changes and slight cramping like I normally do, and well...it was our honeymoon. So there was ample opportunity for it to happen that day and the days surrounding it.

Fast foreword to last night. Which would be dpo 6 going into 7. I slept maybe 3 hours. Heartburn, extremely hot randomly, and super crazy dreams kept me awake. There's also been some light cramping on my lower right side like a little towards my hip. Not even period cramp level, but definitely there. And the random crying at everything. Heartburn isn't abnormal for me, but it's usually an hour or so after I eat something acidic. I did have pizza. But that was almost 6 hours before I laid down for bed so I don't think so, but could somehow be it.

I did take a hpt this morning (because I have no self control; BFN of course).

Just from what I remember from nursing school implantation normally happens around 5-7 days after fertilization. So it would still be a little early to test. I'll probably wait til the end of the week to try again, but does this sound familiar to anyone?

I'm hella good at not getting pregnant, but actively trying to is a whole new beast for me. Little advice/comfort would be great.

Does this sound like pregnancy stuff to you guys? Trying not to get too optimistic over here.
