advice needed

Hey ladies looking for a bit of advice, I'm currently ttc baby #3 but with the stresses of life I have kind of stopped tracking, I was using opks and bbt but my body has began to play tricks on me the past two months, what I'm concerned about is that when me and hubby bd I seem to get a big blob of ewcm that's tinged slightly with pink spotting, (tmi sorry) it only happens after I have been to freshen up and nothing else is seen this has happened to me 4 times now and not being everytime we have bd, all times it has happend it has been in our normal missionary position, but this is something that never happens to me, I also never really get ewcm at the best of times, and I'm not sure when I ovulate (cycles range from 25-30days) last cycle I had a 27 cd length but my af was quite light and I didn't clot as normal, I stopped doing my bbt as it was all over the place which again is unusual. I usually have a clear shift in temp but last month I haven't. Does any ladies or has any ladies had the same thing happen to them? I'm scared that this might be some type of infection (if that's even possible) Iv had really weird symptoms and apparently my peak day is meant to be today, only I don't feel like I have ovulated or I'm near ovulation. Iv had sore boobs and slightly tender nipples since af with lower back pain and I have also just recently started getting over a cold or some type of viral congestion bug... I'm very moody and irritated most of the time. And I just can't be bothered to do anything. It's also putting a bit of strain on our sex life as I'm always aware that this might happen and although it's very little I'm scared incase it turns into something more, getting an appointment at my Drs is like getting blood from a stone but I have one organised for a few weeks time, but I thought I would ask ladies in the forum incase someone had experienced this before or knows what it might be. Please help 😞
