So I had Sex a little over a month ago and about 1.5/2 weeks later I had my period but it was extremely light and I was telling my friend that lives with me that was also on her period said 'you mean like spotting' which made me think maybe I was spotting but thought it was my period bc it was like 2/3 days lighter than my normal periods and the month before I was almost 2 weeks after her which is weird we were on it at the same time. and now it's like every morning I feel sick and every time I eat. and it scares me to think i could be pregnant ? is it even really possible or am I over thinking it?
