Okay so i had "sex" february 21. The reason i put quotation marks is because he didn't cm inside me he just kinda went in and out of me maybe 6 times and then i asked him to stop because i didn't feel comfortable because we weren't using protection. Okay but here is my problem my lower belly feels firm i don't know if it has always felt like that and i have never realized it or if this is new and i'm pregnant. I took 4 pregnancy test in march and another 4 this month and they all came out negative. i have had all of my periods since then i don't really have any symptoms maybe dizziness and slight nausea if i chug my water.
