Hello. I Have Felt Very Weird The Last Few Months.

Hello. I have felt very weird the last few months. A couple days after I ovulated, I started to feel this weird pressure in my pelvic area. Almost like the pressure you feel at the start of an uti, expect no other symptoms followed. The next day, I started getting kind of like pinching pains in my abdomen a few times a day. It started around my navel and switched between sides for a couple days. Since then, my nipples keep getting hard and they hurt. Even having clothes against them hurts. They get this tingling sensation every once in a while too. I've also felt very tired, moody, nauseous, and nervous. I really started feeling like pregnant. I keep getting headaches and being bloated. I believe I have gained a few pounds too. I always have a regular cycle and I'm three days away from expected period. Yesterday I started feeling crampy but they were very light. Then I noticed faint blood. When I woke up this morning it got a little bit heavier but not like my regular period. The cramps have stayed light all today. Usually my period is faint for an hour and then it becomes heavy. Also the cramps are horrible. This is not the case here. I have also noticed I am not really getting any blood clots which I usually do. I can tell this is not a normal period. I just haven't felt like myself.
