I had unprotected inntercourse around 6-7 Aug which was a week after my period ended and then took i pill within 24hrs. I observed some bleeding for 3-4days a week later. Then i had another encounter. Unprotected but no ejaculation. My period date was 26-27 Aug... I took 3 urine pregnancy tests. All were negative.. 1st one when I was 2 days late and 2nd and 3rd when I was 7-8 days late. I was told that I will get my period around 14th Sept.. I did observe very light bleeding from 14th till 18th. I took another urine pregnancy test today and it was negative.. Should i get the blood test or I can expect my next cycle to be normal?
