PERIOD CAME BUT HAVING PREGNANCY SYMPTOMS!!

Hi, I'm 21 and my case is a lot weird but everything leads to pregnancy or so I've found through research. I had unprotected sex on 11/11 (Sunday) and my period actually came a whole week early on the 16th (Friday). When it started, I had really light pinkish blood and barely anything which is abnormal for me because I usually start full force. Anyway, the next day. went to the restroom and it was still the same, it started to come a little more heavy towards the end of the day. Had a regular period from that day on for about 6 days. It went off I believe on Thanksgiving (22nd) and on Friday I started coughing out of nowhere at dinner and within a couple hours, I got sore throat and started losing my voice. I found that odd because I had just gotten over a cold maybe two weeks before and I'm not the type of person to get sick more than once a year esp. that close together. Nose started to get stuffy and I kept having this bad cough. I've been taking NyQuil Liquigels for the past week and it has not helped my stuffy nose at all. It helped my cough a little and my sore throat went away but the stuffy runny nose still remains through it all. That Saturday (24th) I had this really bad feeling at the very bottom of my stomach moreso towards the left quadrant of it which felt a lot like ovulation except my period had just finished two days before. I had to unbuckle my pants and everything to take some pressure off of it but it really felt sore like to describe the feeling better.I also have a lot of clear to white odorless discharge that comes and goes and sometimes, it leaks out when I cough or sneeze. I wouldn't say I pee a whole lot throughout the day but I can say that I have to urinate a little more than I used to and closer together. Sometimes I have to go even when I don't drink anything and the urge is really bad to the point the minute I feel it I have to go or I would nearly urinate on myself. Sometimes urine would leak out before I make it to the bathroom but it doesn't hurt my stomach or anything like it did when I had a bladder infection and it's always a generous amount coming out each time I go to the restroom, never a strong urge with barely any urine like the bladder infection. Just a few hours ago my stomach suddenly got queasy like I had to throw up but wouldn't throw up. To describe it better I would say the feeling was just like when you've had too much to drink and you sit down in one place and your stomach starts to feel real uneasy but you don't neccessarily throw up but it makes you really uncomfortable. Only difference is I didn't have any alcohol. Now my stomach still feels uneasy but not as much and my head is starting to hurt a bit. I've been having to deficate a lot more too. I don't know what's going on but I'm really confused and I'm trying to have an explanation for everything I go through to psyche myself into thinking that it couldn't possibly be pregnancy. But everytime I research something I'm going through, it points to pregnancy! The only thing that gives me hope is the fact that I don't have tender breasts or increased appetite or anything like that and I've had my period for the month. I don't understand. Somebody please help me!!! I'm so confused about this whole mess!!
