Im in the uk its cold and none stop raining it just gives me the worse headache afterwards
I'm 24wks and the same tying has been happening to me. I heard that nose bleeds are very common in pregnancy. Also, idk where you are, but the weather here is very very dry and cold right now so it makes it worse! If they become out of Control I would ask your midwife or even call them now to help put your mind at wase, but I wouldn't worry about it
