Lately I've been worrying like beyond control almost about being pregnant. I am 18, and have been sexually active with my boyfriend for the past month. We have been having sex on a weekly basis, but protected with condoms. It has been about 10 days since the last time we did. I know that you become a lot more aware of body quirks after sex, but I have been stressing out like crazy with the what ifs. To the point where I believe my stress causes me to imagine I have slight cramping and suchlike. While my discharge still remains clear, Today I noticed a little bit of spotting but I do not know what to think of it. Could it be due to my excessive stress and worrying? I have also been scratching to the point of bleeding because of itching (ive always had itching.. I've been tested but negative for STDs) the blood of my pantyliner could very well be from that, but I just don't know what to think.

I do not know what to do at this point other than wait for my period which I am expecting in ten days. I'm pretty sure its too soon to get a home test done.
Anyone's thoughts and advice is deeply appreciated! Thanks
