Long-time lurker, first time poster hoping for some words of reassurance 
For the last approx 10 months I have had occasional spotting after sex, which tends to only happen if sex is in the week leading up to my period? Its very light and only seen immediately after (on wiping)- I can then go months before it happens again. It happened again a few weeks ago (last time was around October) and so decided I really needed to check what was going on. I came off all contraception just over a year ago having had the implant from 2013-2020 and been on the pill from 2002-2013 apart from two 1 year breaks when pregnant in 2008 and 2012.
My last smear was August 2019 and all fine, all smears to date have been clear. GP checked my cervix and took swabs said all looked OK but I did bleed a bit when she did the exam- this was about 5 days before my period started.
She said she would refer me for an ultrasound and transvaginal scan as next step. My appointment is still a few weeks away and I'm doing my best not to worry (have had horrendous HA in the past) but it is niggling away at me that I left it too long before going to my GP, even though the episodes of bleeding were often a few months apart and never consistently re-occuring.
Guess I'm just hoping someone might have had something similar happen to them and all was ok- maybe hormonal or something?! Trying SO hard not to catastrophise my thought right now, any replies would be appreciated!
