Hi doc. I have pcod and I am on krimson 35 on a daily basis. I had unprotected sex on january 16. I also take an I pill after 30 or 50 mins of sex. I also have not miss my any period till now. I also tested prega news in january and february and both the times the result was negative. Yet I feel tender breast, increased weight, mood swings and many such changes. Please tell me are these signs of pregnancy. I am very much worried. Please tell me how I can find I am pregnant or not. If you think I am pregnant then tell me some medicines to avoid this pregnancy.
