I posted in another group as well but I need help

So on here it says my period is two weeks late and I've been cramping and throwing up and sleeping in a lot. My breast are a bit tender. The first week I started spotting but it was really like one dot of blood and it stopped this week also. The cramping only happens when I put on pants unfortunately. I haven't been able to go to school and I can't eat without it coming back up depending on what it is. I checked a pregnancy test and it actually came back blank after waiting an hour. I can pick up another tomorrow but I need a way to do it without my mom and sister seeing when I go to the check out. Also My boyfriend and I broke up because he didn't tell me he got his ex girlfriend pregnant while him and I were together and he's telling me he'll fix it if I'm pregnant and he's talking about buying me a drink. If I am pregnant I plan on keeping the baby tho I've lost a lot of friends because of the situation so maybe it's just stress?
