Hi, I had unprotected sex with my boyfriend on june 11th. May 12th was my period date. While intercourse he didn't ejaculated inside me. On the day of sex I took primolut n tablet. On 17th june I visited a doctor she made all the tests and said negative pregnancy. She gave regestrone tablet for 2 days two tablets each time thrice a day. After that tablets on 27th I had vaginal bleeding which I had similar to every time periods and lasted for 3 days. But generally my periods last for 5 days. Cbp test showed that my hemoglobin and blood levels are low. And all the home pregnancy tests I have done on 20th june, 24th june, 2nd july, 9th july are negative. I'm I pregnant?
