Unsure if pregnant

[Mel34567]

My period has been really weird this month. I usually have normal periods that last from 6-8 days. No more or less. It's always on time too! Well my last period was on August 3rd to the 10th. I had sex on the 24th and 25th without any form of contraceptives. Two days after I had sex I had a tiny bit of blood when I wiped. It was pinkish and it was just one small drop. After that I was getting really wet. Like at first I thought it was just the *** coming out but then after a week I was still getting wet and the discharge started off milky and creamy then it was clear like egg white and then it was a pale yellow then back to white and creamy. I was soaking my panties up and I kept thinking I was on my period but every time I ran to the bathroom there was no blood. Oh and the discharge was not an infection I checked !! After the discharge I started spotting on the 2nd of this month. It was also a tiny drop but there was alittle bit of discharge coming out with the blood. It was milky and thick at first then it looked like egg white. After that on the 3rd I was spotting but it was barely anything again. On the 4th I was bleeding on and off. It wasn't really heavy it was medium to light. Then on the 5th the same as the 4th and on the 6th I started spottin on and off and blood would only come out when I would go pee and around 4 o clock ish my period stopped on the 6th. And I just started spotting only when I went to pee. My periods are usually really heavy from the first day till the fourth day then they get lighter. I've been having really bad Back pain but it's not the usual like I get on my normal periods. And my boobs are aching like crazy. Usually they only hurt for the first two days of my normal periods. My boobs have been super tender for a week and a half now. And at night it's uncomfortable to lay down on my stomach. Also I start to get naseous when I'm about to go to sleep at night. I took a pregnancy test on the 6th in the morning but it came out negative but I was still spotting. Could I be pregnant or is this my period ? How long should I wait to take another test ? Also on the 4th and 5th when the bleeding seemed like a normal period I had some clots but they didn't look like they normally do. They were coming out really sticky like with egg white discharge but it wasn't a lot like it normally happens. After those two days my period was super light. I'm unsure if I could be pregnant or this is just my period. I don't know how long I should wait to take another test?. The weird thing is i feel really off and this just isn't normal for me.
