prego?

so me & my boyfriend have had unprotected sex for the past 3 years, i’ve never gotten pregnant. Well, lately we have been trying for a baby and we haven’t been pulling out. I had sex 3 weeks ago and my period was suppose to come yesterday and didn’t, and I was discharging bad this morning. Thoughts?

keep in mind.. i’ve take 2 pregnancy test before ( 1 last week & the week before) and they both came out negative, i don’t know if I took them to early or what.
