I'm 20 yrs old. 3 weeks ago I had a chemical pregnancy/miscarriage. Five day later the bleeding stopped. Every since then I've been having unprotected sex. On the 31st of oct. I saw the clear stretchy discharge, bu that was the only day. I'm sstill learning my cervix. Now I have mild cramos for about a week now and bright blue veins. I know that was a early sign. Guess I'm asking could I be pregnant & when should I test?
