This is really strange, some days ago I couldn’t breathe normally. I mean that the only thing that I could do is to breathe shortly and very fast. I tried to do some deep breathes but it was very hard. I also tried to yawn because I thought that this could help me to pass over this situation. The things got worse after trying this yawn tactic because after this I noticed that I started to yawn without controlling this and now this thing makes me feel uncomfortable. There is something else; I started to take the birth control pill in that day when I had this strange feeling for the first time. I don’t know if it is linked with my breath difficulties but this pills are one month expired, I asked my doctor if there will be something wrong but he said that it’s okay and that I can use this pills. I’m really very desperate about this thing and I don’t know how to react now. I would like to stop this sensation and to feel myself better. Can somebody tell me what is going on? Do I have to be worried about this or it’s nothing strange?
