I had unprotected sex twice, I am 3 weeks late on my period, backpain, tired, always hungrey, frequently urinating, food craavings. I tried tests bbut doctor said it was too early. So I did a blood test and I'm waiting on results. And then on exactly day 3 weeks I started to bleed. It was light and bright pink and bright red and only lasted 3 DAYS! My period is always heavy and dark and lasts 7 days! Is this implantation bleeding?
Look there are chances of you being pregnant. Consult a doctor.
And sore breasts, and a lot of bloating.
