implantation feeling

I had my last menstrual period on July 7-July12 and i think i was ovulating around day 21 because my next period is Due August 5. I had several 5-8 days of mild cramping after ovulation and now i have some breast tenderness and very thin cervical mucus. Do you all think there is a possibility of me being pregnant? This was the first month me and my husband have been actively trying to achieve pregnancy.We had intercourse from the 17th to the 28th every day. If i am not pregnant does anyone have any suggestions?
