I was wondering how many of you have had a regular period while pregnant. I really don’t think I could be pregnant, but I’ve been having nausea terribly over the past 2 days, but I also had really bad diarrhea. I’m only familiar with the pregnancy symptoms everyone talks about, however, my husband says that his friends wife had 2 period with nausea and vomiting when she was pregnant, so I’m really just confused. Any answers will be much appreciated.
