Throughout my pregnancy I've experienced several nosebleeds, but usually they are stopped quickly and don't happen more than once or twice a day. Yesterday I had a nosebleed three times and then another one as soon as I got up this morning, and before yesterday I hadn't had a nosebleed in a while. Each time my nose bled it was after I blew my nose gently, and each nose bleed lasted at least a couple of minutes.
How can I prevent this and/or stop it quickly? I'm a teacher and I'm horrified to have this happen in front of my students.
