So my period was suppose to come on the 30 . I tested the 29 . (BFN) im not currently late . I had sex on the 18 ... Is it still possible to be pregnant and there isnt enough to detect the pregnancy test yet ???  Should i test again today or wait a week ??? I been feeling dizzy , pain on my left lower stomach , nausaus and my apetite has been going down . Also my sex drive is waaaay up . Lol . Please comment . Hoping for my rainbow baby !!
