We’ve actually been avoiding TTC, just because we want a spring baby 
(it’s just how we always pictured it) and then I had an operation after a cyst on my ovary burst. Anyway, we actually ended up having unprotected sex on a day I was ovulating (according to my app). I’m due on my period this week, I’m a bit irregular between 28-34 days, I noticed yesterday a pink colour in the discharge when I wiped (sorry tmi) but was a very small amount and it is still there today, initially I thought this as my period (it’s usually very light anyway and lasts 2-3 days) but it’s different than normal and thought that this could be implantation bleeding? I have no other symptoms, other than my breasts feeling sore but I get this as pms anyway so not unusual, and I have a tiny bit of cramping on both side of my lower abdomen. I have taken a pregnancy test and it was negative, so I’m a bit confused. Thanks in advance
