Welcome! How can I help with your medical question? my normally have 28 days cycle. i had last period on the 7th of june to 11th of june. and i ovulated from 13th till on 15th of june. And i had unprotected sex, during my ovulation period. i am suppose to see my next period on the 4th of july. But i started having light bleeding which is pinkish and brownish colour from 27th of june till today 5th of july. which is 9days now. I don't know if it is implantation bleeding? and when can i go for pregnancy test? Have you seen a doctor about this yet? What medications are you taking? have not seen doctor yet. and have not taking any medication. but i only took panadol this morning, because i was having back pain Anything else in your medical history you think the doctor should know? nothing
