Hi, I had my period on time, but only lasted 2 days but was not heavy and went a brownish colour. Have bloated feeling in belly, back ache, blocked nose but no cold , feeling sick change in food. Did pregnacy test but negative? Last period was 11th December, did have sex with husband when ovulating. had slight bleed on 15th Jan as i have 35 day cycle. could i still be pregnant but to early to show?
