My period was Oct 13-Oct 17th. two days after my husband and I had sex. no protection except pulling out. a few days after I went to go pee and when I wiped there is slimmy discharge on the toilet paper with dark brown in the middle. Ive been queezy and actually throwing up. The smell of some cleaners get to me and cause me to throw up. I know most prego tests cant detect this early since im suppose to test next Friday. Now my lower back hurts over my kidney. Im 23 years old and I think im pregnant but don t know if there is a test on the market that can dect this early.
