Could I be pregnant, or is this due to an irregular period??

I sort of had 2 periods last month.
My regular period was on April 16th, but then 1 or 2 wks later (i can't remember when) I started having a really light/spotting period that lasted a while.

I was suppose to start my period last week (may 16th), but I didn't and had no signs of starting it. I thought this was because my period was so screwed up last month. I then had protected sex that weekend, but I am always such a worry wart when it comes to sex. I never trust condoms (I'm going on birth control soon)...I always feel as if it can leak at the base of the condom or something like that. I also worry about little traces of sperm possibly being on his hands or on some surface and it touching me. Also note, he didn't finish and when taking off the condom each time I saw it was fit snug, but I still worry =/

(I know it's pretty rare that someone could become pregnant from this) BUT what also worried me is that when his penis would lay on his stomach before putting the condom on, a little amount of precum would get on his stomach. After we put on the condom, his penis touched his stomach again and I was worried that that small amount might have gotten onto the condom? He wiped off his stomach and then I kept wiping off the condom with a cloth.


Am I getting too paranoid?

It is now May 26th and I still haven't gotten my period. I am getting sore breasts as I usually do when I'm about to start, but still no sign of my period. I also read that sore breasts could be a sign of pregnancy?!



Now I'm confused and nervous.
Are my periods just THAT irregular/ screwed up from last month and stress could be delaying it more?!

Or....?

Please let me know!
Thank you in advance.
