So my boyfriend and i had unprotected sex (and lots of it) on the 28-29 of September! My ovulation date was the 4th of October. I started having symptoms of pregnancy almost right away (fatigue, dizziness, bloating, cravings, nausea, constipation/diarrhea)so pretty much everything but breast enlargement and extreme tenderness (only my nipples were a little sore at night by the way i do have large breasts). anyway 3 days before my period was due i began having dark brown discharge which is typical before my period but it usually lasts a couple hours, instead it lasted a couple days. when my period did come it was different it was almost half discharge (the watery kind) and half blood. there were very small almost dot like "clots" and toward the end i had 2-3 clots the size of a pencil eraser (again pretty small). it lasted 3 days and not the normal 4-5...but the discharge lasted about 3 days and isn't white like usual but like a gray/yellow color. now it's been just a little less then a week since my period and my pregnancy symptoms are coming back. I've been dizzy, nauseous, either constipated or had diarrhea, i'v e gotten a couple of those pimple like bumps around my nipples, I've been urinating a lot and drinking a lot more (like the past couple weeks I've drank almost 6 gallons of milk on my own...so even though i had my period could i be pregnant?
