Wondering???

Ok so here is my story I miss a period every third month and I did that last month not uncommon at all n now I am getting close to my next one but now I am just having some weird signs I feel like most of it is just pmsing because of more hormones but I have not had before so here they are

Tired

Cranky

Very moody to things

Headache

feel sick at random times of the day

Cramps

Pelvic pressure in the morning

Pain in my hips

Back pain

More blue veins on boobs

I know you guys can't tell if I am pregnant or now but advice would be nice my friends are all hrs away so its hard to talk to them right now so advice what you think could be going on other then just pregnancy or if I sound very pregnant in your mind and just get over my fears and pee on a stick
