if you could just give me a short reply with your opinion that would be greatly appreciated

Here lately it's like no matter what I do or what my boyfriend does he always makes me so mad but it's not just him it's everyone and I'm not ever like this but here recently somebody can drop a pin and it hit the floor and I just freak I get so angry.... and I really don't know why I'm getting so angry over the simplest things.... i'm in between ovulating and my next period...... closer to the next period Though could this have something to do with my period or ovulation but like I said it's just something new could I by pregnant I mean there's always a chance because me and my boyfriend are trying for a baby ......but I wouldn't have horrible mood swings like this so soon would I? I don't know I just feel like a horrible person right now and I really just don't know what to do.
