So my husband and I just started trying to conceive last month. My monthly is due tomorrow. I woke up with minor spotting when I went to the restroom and thought it had come a day early. But that spotting was it. Nothing else all day. Could it be implantation bleeding? I feel like I'm running to the restroom more and woke up a couple days ago SICK. Trying to not get hopes up too soon.
