HELP!!!!!! ANYONE!! TTC.. Period

Okay, ladies..
I've been ttc for about 6months. Due to a miscarriage in September of last year...
Now recently I've had intercourse on Vday(ovulation time) right.. So to make a long story short, idk if it was my period or not but I bled for a few days first day was heavy but it just flowed. And the rest of the days it was light. But here's the catchy part since that and before the bleeding I've been tired and lazy, nauseous, very moody and breast pain/breadt tenderness. However, my breast do seem fuller and bigger.. The syptomns are still in tact as of now my breadt are hurting like crazy. Is there any chance that I could be prego?
