Trish, thanks for the links! Yes, also my gums are bleeding a little. That happens to me some other times, too, but I don't think it's a coincidence it goes together now with the nosebleeds.
Bernadette - Oh no, I think I made it sound worse than it is! It's not like my nose had been bleeding constantly for two days, but - yes, sorry for TMI - more like suddenly getting these yucky clumps with clots in my nose and throat. So I mostly notice it, when I blow my nose (and I don't have to do that often, not having a cold), and then after that the bleeding might continue on its own for a little while.
So it doesn't seem anything very alarming, but still something I haven't experienced before.
Mrs.spit - no, I'm not on aspirin. I'm in Finland, and we're heading towards spring now, so the air is not very dry anymore. I have a prenatal check on Monday with a nurse, and I'll ask for a referral to blood tests to see how my platelets are just in case. They have been fine so far (354 at the beginning of Feb, and 295 at the beginning of March).
Sush and Theartsymom, thanks for sharing about your experiences with BP meds!
