OK so on December 4Th i had unprotected sex with my boyfriend again on the 5Th, the 4Th was the day AFTER the last day of my period. then on Monday i woke up and it felt like i had a tickle in my stomach and slight cramping and had slight brownish bleeding but brushed it off thinking it was old blood. the "tickling" in my stomach continued all day and also into Tuesday and Wednesday. on Tuesday i had what felt like diarrhea but not really watery. i have also been very tired lately. today is Thursday and i was getting ready to shower when i went to the bathroom i looked on the toilet paper and on it was a jelly like dark brownish discharge. that's when i started to think maybe i am pregnant. i plan on taking the test to be sure but i would like some opinions please! is it really possible I'm pregnant after having sex right after my period? and could i be having symptoms so early? i haven't had the lower back pain or swollen or sore breasts but i figured it was enough to ask.
