TTC #2- Help!

My boyfriend and I are trying to conceive #2, I had my paragard removed Feb 2, and we dtd then and the days following. As far as my cycle goes, I do not know when I ovulate, and I’ve always had a bit of an irregular cycle (my last period was Jan 12-17) Anyway, about a week before AF I usually get bad cramps, bloat up bad like a balloon, get very irritable and “b*tchy” and get an insatiable appetite. That’s about it though as far as my usual pms goes. I haven’t had any of that this cycle though and it’s around that time when I should expect my period to start. Instead, I’ve been having very light cramps, nothing like my pms/period cramps at all, my boobs look and feel fuller and heavier, I’ve been nauseous and queasy on and off since the 2nd and I’m bloated, but not as badly as I bloat when I’m pmsing. My appetite tapered off last week, but it’s picked up to a normal level this week. I also just “feel” pregnant, just a constant ‘weird’ feeling in my lower abdomen, though I’m chalking that one up to my mind just reallllyyyy wanting to be and playing tricks on me. I’ve been emotional too lately but way more weepy emotional, whereas when I know I’m pmsing I get the angry and irate kind of emotional. As far as cm goes (sorry, tmi, but helpful info) it was clear and thin and very fluid Feb 2 and the days following and then A week ago I noticed a milky white, thin and watery cm. Over the week it’s gotten thicker and in less amounts and today Ive had barely any discharge, though what was there was white and thicker. I’ve taken 3 pregnancy tests so far, 2 of them today, and they’ve all been BFN’s 😔 is it still too early? Is this all in my head? What do you guys think about my change in symptoms? Any input appreciated.
