Fingering, precum and changes for pregnancy

First of, I live in a non-western country, and there's no sex ed here. Only thing remotely to sex ed that we got is "Use condoms, AIDS is bad". This is gonna be long since I want to include every detail, but I'm gonna include TLR and the bottom.

I did a bit of research, and apparently it's rather unlikely to get pregnant with precum on fingers. However...I do have a few concerns.

I have this FWB, and over the past month I rubbed her clit on three different occasions. There was also some dry humping (with underwear on both of us) involved. She keeps a close eye on her period, and we fooled around outside of her ovulation period.

The first time I fingered her, it was a day of two after her period ended, so no ovulation yet.
The following encounters occurred a week after her ovulation, so I guess no egg to fertilize. I know that fertile days aren't the most reliable for of "contraception" but I'm trying to analyze everything.

Anyhow, before I see her I make sure that I don't masturbate for 30h, and urinate a couple of times just to get any leftover sperm from my pipes.

So yeah, the two times I saw her, I never touched my penis, so I didn't wash my hands beforehand and I rubbed her clit, also I got my fingers wet from the vagina entrance, just too keep the playing field nice and smooth.

The third time, I played with my penis a bit, and I got some precum on my fingers. Went to the bathroom, grabbed some liquid soap and washed it, just to be safe and towel dried it. And then I started to play with her clit.

So I'm guessing that I didn't had any precum on my fingers. There was some dry humping involved but we remained in underwear the whole time. It's possible that she played with my penis and then played with her pussy a bit, but I'm not sure. I usually remind her to wash her hands frequently, just to be on the safe side.

Now I have to mention that I haven't ejaculated while with her at any time. So no ejaculation at all.

However, her period is late, or acting weird as she describes it, so I'm starting to get worried.
On the other hand, she had a lot of stress right before her ovulation, she even had a bit of blood in her underwear after an extremely stressful situation at work. To top it off, her thyroid was swollen, so it's possible that her hormones and stress are acting up and that's the cause for this issue.

So...under these circumstances, I'm I overreacting or not?

TL : DR:

• Rubbed a girl's clit outside of ovulation period.
• Didn't ejaculate for 30h or so before the encounter.
• Dry humping in underwear was present.
• She was under extreme stress a few days before her expected ovulation. Had a bit of blood in her underwear that day.
• Period is late, missing, acting weird.
• There was no ejaculation, penis in vagina penetration involved at all.

Should I be worried?
Sorry for the long post and TMI, but I wanted to share as much info as I can just to be sure.

 

No, you shouldn't be worried. If she's pregnant, get a paternity test.

 

Thanks. I know the probability is almost zero (I've fingered girls dozens of times, and nothing happened), but I keep stressing about it.

 

why don’t you fuck her?

 

She can’t fall pregnant from your fingers.Relax.

 

if she's still pregnant 16 months later, take her to a hospital NOW.

 

you didn’t even fuck her! Seriously dude?

 

She could be a rhino in which case, any day now....
