Ok so on may 8 I found out I was pregnant, so I called the doctor they set my first appointment for June 27th based off what I thought was my LMP . I have a pretty regular period average 28 day cycle I only have 4 day periods, in march my period was supposed to be on the 1st but I didn't start until the 6th, and in April I got it the 5th,6th,7th but super light couldn't wear tampons.
