So I had a period july 8th. I missed my whole august period and got my september period on the 12th. Now so far I am late 6 days on the month. I'm not sure if itit's because my periods are starting to go irregular or that I could be pregnant. People tell me you can still be pregnant and have a period but it seems a little hard to believe. But what would explain missing the whole month of august ? Idk. I just need some advice. (I am ttc) . I also have beem throwing up since yesturday I'm not sure if its just flu because its going around. .
