My period has always been irregular, so I stopped keeping track of it, and I'm not on any birth control, I had sex around 5am on July 7th and again on July 11tu around the same time. Around the 16th and the 17th I started having drownish discharge and pains that my pregnant friend told me may be implantation pains, and light bleeding. But last on the 17th I started actually bleeding. So I was wondering if even though I think I started my period (it's still kinda light) if I could still be pregnant? Thanks for reading. X
