good afternoon so to start on the month of july i was feeling really bad tenderness/pain on my breast for about 2 to 3 weeks so i thought i was about to get my period and then nopthing so i was late and received it until july 31 and only lasted till aug 4 which was wired because i always get my period normal but i did do a pregnancy test on july 29 which came out negative okay so now sept is coming and i have not received my period again and i wanted to ask can it be possible that even though the pregnancy test came on negative ion july i can still be pregnant?
