Early pregnancy vs period signs

Ja

WARNING: Long post 😅

Why do they have to be the same?! Like I'm freaking out over here, I would love to hear y'alls input.

My period is due in 3 days and I've been having an array of symptoms that could be my period coming on or that I'm pregnant. I will be getting a HPT tonight, I wanted to wait as long as possible to see if my period would happen but I'm getting very anxious.

So my husband and I are not specifically trying for a baby and the only BC we use is condom/pull out, which I know is like just asking to get pregnant but it is what it is.

We have a 3 year old and one specific sign I had with her early on was that my legs, more so my thighs, were super sore. And that just happened last night and right now they're still sore and almost feel like I have like a sun burn on them.

First sign I noticed "this time" is that just a week and a half ago (I think) I went to pee and when I wiped there was a small amount of light pink/brownish blood on the tp. Not on my underwear or even in the bowl from what I could tell. So that was weird. Implantation bleeding maybe?

There was also one day where I just felt exhausted/fatigued. We were on one of our walks we do every other day and it wasn't just the normal "I'm tired from this walk", it was just exhausted, I just want to lay down.

There was one night last week, we were eating dinner and it was really yummy and all of a sudden I felt like I was about to puke. Like i was literally thinking great I'm gonna have to sprint upstairs to barf. I didn't barf and was able to keep eating after a few minutes cause it was good and I was still hungry. I think there was one more time where I felt somewhat nauseous in the last day or so but it wasn't like I'm about the puke.

I've also been getting kinda dizzy/lightheaded.

Then today I noticed my breats felt fuller and heavier and slightly sore.

So yeah. Everything I read always says well your either pregnant or your about to get your period. I would be more inclined to think I'm just about to have my period with most of these symptoms but the fact that my legs are really sore makes me really lean towards possibly being pregnant.

Again I will be taking a test within the next day or so, just because I cannot wait for my period I'm just so anxious.

I would love to hear y'alls opinions and experiences you've maybe had with your second(or 3rd, 4th, 5th etc) pregnancies. If you had any like definite similarities, which I know every pregnancy is different but there are times where the like one same thing happens and that how you just "know".

EDIT TO ADD: I've also been super itchy, mainly my arms and legs. Have also had some pain in my right armpit, and TMI but some diarrhea as well. These are not normal symptoms for me that would make me think my period was about to happen.

Thank you and sorry for the long post!
