Bleeding Irregularly?

Hey guys. So i'm 17 and recently i was fooling around with my girlfriend for the past month. Protection was always used; we also filled the condoms afterwards with water to see if they broke (none broke!). We're not really equipped financially or emotionally to have a baby so i hope this issue isn't pertaining to the beginning of a pregnancy. So her cycle has been really irregularly this month. Her supposed "period" occurred really late; about 36 days after her last one.

During this time (she's not on her period - time) she's having a stress attack because she thinks she might be pregnant. SO i try my best to calm her down during these times (you know, like making a bracelet for her and all that boyfriend-girlfriend stuff.. i suck at arts and craft.) and eventually she got her "period."

However she had doubts about it because it was so late and maybe it's because of implantation bleeding. (Her wild idea) Now I'm having a stress attack too haha.

It was a really weird "period" too. It lasted for almost a week when her normal periods are at most 3-4 days. So we cleared out minds and she had a wedding to attend so we've been separated these past 2 weeks. I wish i was there for her during this time but i couldn't just follow her to her cousin's wedding; that would be weird!

During the wedding, we keep contact and she informs me that she has a fever which is kinda weird since it's summer and her body's feeling weak from the fever (not sure how high it was, she never told me). So i wish and hope that she'll feel better for the wedding! Wedding's over; she shows me all the pictures she took and whatnot.

Then she informs me that she's bleeding down there; which frightened me and her because neither of us expected this. So now we're having stress attack v2.0 as we're doubting whether she did have her "period." This bleeding started about on the 5th/6th of this month (3-4 days hiatsus) and today is the 13th which is kinda of a little too long to be bleeding. She said it's not a lot either; i don't really know bleeding terms but i guess that's spotting?

So I have this half-assed theory that she was pregnant and her fever terminated the pregnancy.. or something like that. I was wondering if anyone would know if this sounds like a pregnancy; i can't sleep at night because it's frightening for me and i can't imagine how it would be for her.

So to anyone out there; does this sound like a pregnancy? Please help ease my mind at night. This may seem like a story but i simply broke it down into mini paragraphs so it would be easier to read and cause less strain on the eyes. Thank you guys for the replies!
