I've been having pressure in my vaginal area & pelvic area lately. Making it feel like I have to urinate frequently. Also I bled which I thought would be my period on may 16th but it wasn't like a regular period. It kept stopping then coming back. I heard of something called a "breakthrough bleed" which is when you conceive too close to your period your body still has not detected your pregnant yet so you bleed anyways. So could I be pregnant ? I really need help
