DP and I are wanting to TTC soon but I'm worried about my periods. This last cycle I had one day where I was bleeding a little after going to the toilet and then a small amount of brown blood on the pad for the rest of the day, then a few days of bare minimum spotting and that was it. This has been pretty consistent for the last 6/7 months. GP is unconcerned, I had a mirena coil removed 9 months ago so she thinks it's probably just that but I'm fairly sure I had super light periods prior to having the mirena. They're reasonably regular at least - cycles seem to be between 28-30 days with one cycle of 25 days. GP sent me for bloods (not cycle day specific, she told me to go straight to phlebotomy) which checked oestradiol, LH, testosterone, TSH and vitamin D. The only thing that flagged up as an issue was low Vit D so she told me to take vitamin D supplements in addition to my prenatal. And that was it, no further investigations until we've been trying for a year.
It doesn't seem normal to have this little bleeding though. Anyone else had similar? Have you ever found out what's causing it?
