2WW symptoms first time TTC?

Hey! This is my first time TTC ever and I’m trying so hard to not get my hopes up over here during my first 2WW.

I’m 10 DPO (waiting til 14 to test), but today I kept having really strange twinges. Some of which felt like pulling and like little lightening strikes in what I think is my uterus area. I’ve never had this during PMS but also usually before AF (3 days away) I’m cramping severely and I’m not and it’s strange.

I’ve felt such new things like hot flashes, sore breasts since ovulation that have developed into heavy severely sore pain bags lol. I’ve also had random nausea, consistent gas, mild headaches, a tough time catching my breath, random dizzy spells and it’s all kind of new and confusing.

If this is your first pregnancy, how are you supposed to know what might be a good sign?!? I’m hanging in there but it’s hard not to be super aware of all this.

Any guidance? Are these things normal? I feel like such a newbie and keep telling myself there’s no way I got pregnant the first cycle.
