Weird period? So confused!!!

Okay so I'm confused on what to do. My husband and I have been ttc for over a year and I have been taking fertility meds for three months now. This past month I finally ovulated nd we DTD before, during, and after ovulation just to be safe. My period was due two days ago.

Normally my periods last 8-9 days (very long...). Usually I have acne breakouts a few days before, cramping, the usual stuff. Also, for a few days before I get my period I get a really bad headache that doesn't go away with medicine that will last 1-2 days before I start.

(if TMI for some, I'm sorry!) On Thursday morning (like at 1am) I started bleeding and throughout the whole day, I had to use about 4-5 tampons. It was like a medium-heavy flow, not too too heavy bad but certainly not light. It continued into Friday and then suddenly all bleeding stopped around 6pm yesterday (and I mean sudden, like bleeding one minute and then nothing whatsoever 10 minutes later). So my 'period' lasted just shy of 2 days. Also this month I had no headache, very very slight to no cramping, and no acne at all. I'm so confused.

For someone who normally has an 8 day period, this is a little concerning especially since I've had none of my previous symptoms for when this time of the month comes. I've read that people can bleed for a few days and still be pregnant but I'm not sure what to do. Today is day 3 in what I would consider my cycle except I haven't bled in over 15 hours at all. I'm supposed to start my next Clomid round today but if I end up being pregnant, this could be horrible. What should I do??? Any ideas from you ladies??
