Wondering if someone has an opinion. We are currently ttc. First day of last period was 23rd July, ended 27th July. We dtd immediately after, every other day since. For the past couple of days I've been having very mild period cramps, not enough to be painful, just so you know they're there. My abdomen has felt heavy and I've had some mild lower back ache. I know it's not related to ovulation as I never get any ovulation symptoms at all, I only get these things the day before my period, literally. Does it sound likely that these could be really early pregnancy symptoms?
