Weird period

Erica
I am a 34 yr old and always have had regular periods lasting 4-5 days with 1 or 2 heavy days and the rest of the days are regular. Me and my husband have been trying to conceive for over a year now and I was on fertility meds but haven't taken any since march. I had a regular period this month and then no bleeding for 2 days and then BAM like I was on my period again. Then it stopped for a few days and now I am bleeding again. This has never happened to me before and I'm not sure what it is???? Has anyone ever had this happen to them??? Please help
