On 18th June I had protected sex, it was 7th day of my period. I was expecting next cycle on 12th july but periods were delayed due to stress I guess so I took 2 preg tests on 19th/20th, both were negative and I took primolut from 20-24th. I had another test on 26th it was also negative. I got down on 27th but periods were short. They ended in 2 days.From past few days I was experiencing mild vaginal discharge & breast tenderness and nipple soreness. I took primolu again on 17th till 19th as I wanted to get periods. Now I got my periods but blood is pinkish red and watery and scanty. Is this normal?Is there still chance of pregnancy? I don't have any other symptoms. Iam attaching pics
