About 4 months ago I gave my boyfriend a hand job and he came on my stomach. I went and cleaned it off and then a couple minutes later he fingered me. I started to worry about being pregnant but my period came. I thought the stress would leave but I was still paranoid. I felt nauseous all the time and my lower back ached and I was really gassy. I took 2 pregnancy tests and they were negative so I thought the stress would leave but it didn't.. My next period came and after I was still paranoid. So I took 2 more pregnancy tests and then later a digital one and still negative. My 3 cycle came and still felt worried. I'm still worried... Why do I feel this way? Could I be pregnant after taking 5 pregnancy tests saying their negative and my period all at the right time? Or paranoid ?

You're paranoid. Do you want to be pregnant, is that why you're obsessing about this?

If you don't want to become pregnant, and you want to stop worrying all the time, then stop playing sex games. No form of birth control is 100%, but, what you described, although pregnancy is possible, it's unlikely, very unlikely, to get pregnant that way.

You've had 3 periods, and numerous pregnancy tests telling you you're not pregnant, so why do you think that you could be?

I would say obsessed and way past paranoid,

First there is almost no chance of pregnancy from this, and after one period you knew you were not. ( no need to any pregnancy tests) after two and for sure after three, you are not pregnant.

So stop testing, and get counseling if this is obsessing your life.
