Pregnancy chances?

Question

On Saturday of last week I had direct genital contact with my boyfriend (no penetration or s***n spilling near v****a) and the next day I ran a 21km marathon (I started running 10kms daily in street and track for a month and half now and never exercised in such a way before). I expected my period to come on Monday but instead I experienced spotting and also on Tuesday, then it went off. Can I be pregnant? I'm very worried i'ts implantation bleeding since he wore no condom...

PS: That was the only contact I ever had with my boyfriend and I'm a virgin.

Answer 1

i doubt it ... when you run your periods tend to be abnormal.  sometimes i'm late and sometimes i'm early.  same thing happens to my friends.

Answer 2

It's probably not likely. The extra stress on your body that it's not used to can throw things off.

If you're really worried, take a pregnancy test. Go see a doctor if you're really really worried.

Answer 3

It is "possible" (in the event of what is referred to as "pre-***") but fairly unlikely.  One possible explanation may be your sudden increase in activity which can throw off the normal cycle
