I need advice ! Please !

My husband and I been trying to have a baby for a little while now since November my af is between 28 to 35 day cycle . My af hasn’t come since January 22 I spotted two weeks after that for 2 days, I haven’t had a period since then in the meantime I’ve been very tired nausea sore nipples and sore breasts, we still continued to still have sex every day/ night I took 3 pregnancy test in the mean time all negative, today my nipples felt very moist with white stuff coming out of my them, I used the restroom today and noticed little blood but my period isn’t due this mouth until the 22nd . I’m so hurt and confused . I know I should see my Obgyn but I’m scared !
