I feel tickly feeling in my uterus

Okay so Me and my boyfriend had sex everyday on the 20th up until
The 26th of april and he came inside of me everytime when i was ontop when he was ontop when he was behind me and i was bent over and i felt it go inside. Now since then things have changed alot . I didnt have a period for a while couple weeks ago i thought i got my period but it was light pink and only showed when i wiped. I was in no pain like i usually am when i get my period and the flow is heavy. I was sleep alll day and all and my appetite has increased and so has my bladder and i put on a little weight. my hips have got wider and my abdomon has been itching crazy i itch on my hands my feet inbetween my thighs my rear end and my breasts. My breasts also have these big green veins that are towards my nipple and there so visable and clear to see when before i never noticed i had veins in my breasts they were tender back in april for a while but now they just itch. I feel tickly feeling in my uterus alot and i feel really sick and dizzy sometimes after i eat my nasua has calmed down a little im
So moody omg i cry about everything and i turned into a little mean girl i get annoyed so easily and i curse alot before all this i had a flat stomache i could see the outlins on the side of ur hips thing and now is like a little poke out there now even when i suck my stomache in. My breasts are heavier tere busting out my bra and im goin nuts with all this stuff if i am pregnant this would be my first and all this stuff goin on with me is new and never happened to me before in my life i never broke out and my diet has always been the same since i was a child. I just need a answer i dont have money for a test of any kind and im afraid to tell my mother or any body Also my lower back kills!!
