What is considered to be an irregular period? I thought I'd ask on here because you ladies give me some good advice. My periods used to come exactly on the same day every month (16th of every month) then coming around 20th - 30th in between there. ( they have been all over the place since August 2017). And the period only lasted 4 days the first day is always spotting then the next day full on period. then the period was 3 days. which is unusual for me and in January my period didn't come til like 27th and only lasted 3 days. And February I didn't have a period at all and I thought I was pregnant but I took a test and was negative of course. And the month of February. I felt nauseous when eating, sore boobs,etc. And then this month March I had spotting on the 5th all day and then the next day full on period but it was a little lighter. Than normal. But that was only for 2 days and the 4th day nothing and the 5th day spotting. And now lately I've been kinda crappy my boobs have been sore, a little nauseous off and on. TMI but yesterday I ate a burrito and threw it up after I ate it. which is unusual for me cuz I hardly ever throw up. And I feel like I'm going to be starting. 😣 Can I have two periods in one month? So my question is a regular period considered to be. A period that starts on the same day every month.? And a irregular period is you have a period every few months? Do I have a regular period? Should I take a HPT? Any advice helps Thank you ladies!!! Much love you you all!!💖💖
