period but pregnant ?!

I know a lot of other people post on here with similar stories and i always think they are crazy, until now. My boyfriend and I have been pretty careless when it comes to using condoms lately. Probably for about two months now. We talked about kids and we don't really want to try right now but at the same time if it happened we wouldn't be upset. He doesn't completely just blow his load inside of me but we will do it multiple times at once so his Precum most likely contains Some sperm. I got my period a bit early , on June 9th when it was supposed to come 5 days after that. My period in itself started out pretty normal and even hit its heavier points. But what was weird about it was it lasted about 10 days (spotting up until this morning) which is weird, mine usually only lasts around 5-6 days. and for the majority of my "period" it was pretty light . It was also darker brown with some light pink mixed in with mucous. For around 4 days now I've been extremely tired. To the point I don't want to do anything. Also things are really getting to me. I almost walked out of my job a few times this past week over simple things. On Thursday night I was laying in bed and had sharp twinges in my uterus and it almost felt like stretching and pulling pains. The next morning I woke up with EWCM and clear mucous mixed with spotting which isn't normal for where I am in my cycle. Which you would think I ovulated but it's not possible as I still had my "period" Usually I'm very dry at this point. I then checked my cervix to find it pretty soft and high and closed which is super strange for where I am in my cycle. I always check it and track everything so I know for a fact this is abnormal for me. Typically for cycle day 8-10 it's closed low and hard for me. Then I woke up yesterday morning feeling so sick to my stomach and it's been coming on in waves ever since. I threw up this morning...Yet I'm still so extremely hungry even when I want to puke. I've had a constant headache for a little over a week at this point that even Advil won't shake. I've been drinking a ton of water because I'm constantly feeling thirsty. And now that the spotting has stopped I'm having quite a bit of clear watery discharge which again is pretty abnormal for me at this point in my cycle. I'm usually dry. I look at myself in the mirror and I even look drained. My nipples also sometimes randomly feel like an electrical current is going through them. Like it'll be sharp pain! I talked to my mom and found out that both her and my grandma had a period for the first month of pregnancy. Now I'm worried that I am pregnant because of the symptoms and weirdness in my cycle, and I'm worried because I've been living like I'm not pregnant, including drinking wine. Do you think it's possible? I plan to take a test soon just to be sure but has anyone else experienced a period but still ended up being pregnant? It worried me that both my mother and grandmother did.
