I had heavy petting on feb 9, 14 and 15. There was no penetration but I knew that pre cum could cause pregnancy too. My period start on 10 feb and it ends around the 15th feb with very very slight bleeding. On 3rd of march till 6th of march I have been having a bloated stomach and heavy white discharge. Sometimes I have this brown blood stains which was too little to stain my panties. And sometimes it was just a lining of brown stains with the white discharge and just small blood clots. (could this be implantation bleeding?) at first I saw the stains after i've wiped, I thought I was having my menses. But as days passed I realised it was very light.. Too light to assume that it was menses. I was afraid that ill be pregnant. Or was it some "old" blood wash out due to the heavy white discharge im having? Is this signs of having a menses soon or signs of being pregnant? Or should I wait later to see if my menses come then I assume anything? Im very very afraid.
