Early period with no blood clots?

Question

I had unprotected s*x about 4 weeks ago like 3 days after my period and my partner did not ejaculate. Just to be on the safe side the next day I took the morning after pill (plan-b) and the following week i got what i think was my period. I was bleeding light pink then gradually went to dark red. It lasted for 5 days and i had no blood clots. This period was lighter than usual because i usually have a heavier flow and blood clots are present. The next day after i finished my period i started to get alot of clear vaginal discharge for 3 days then very little. I was supposed to get my period on the 20th of August from my last regular period before i took the pill and i didn't get anything yet. So what i want to know is the bleeding that i got was my period? Also are these symptoms of pregnancy and can i be pregnant? And did the pill work and i can't be pregnant? Please help i'm very worried.
