My period is irregular at times which means my cycle length is about 35-45 days. The last of my period was on June 20 and did not get it on July nor the beginning of August (knowing I'm sometimes off) so at some point I thought I was pregnant ..but I tested negative. It's the 19 of August and I just got my period. Is there something wrong with me? I mean for about 2 weeks before my period I felt awful like nausea and cramping. I'm kinda in shocked because this seems a bit wierd.
