I am a bit worried...

I have a irregular period.. My Dr gave me a pill to start it, scent I have not had it... in about 2 going on 3 months...

She said as soon as I take it, a few days later I should ovulate and then have my period. Then she wanted to start me on fertility pills. (I am trying to get pregnant.)

Well I ovulated two days ago, which I didn't know till my hubby and I made love ( I have a ovulite which tells me when I ovulate and didn't do it till that night) well yesterday I went potty, whipped and there was just a small spot of blood. I didn't think anything of it. Then this after noon, I went potty and whipped and there was blood. As if I just stared my period and caught it in time before it hit my undies. It was really light blood, but now is looks as if my period is about to end.. its a brownish red color...

I cant take a pregnancy test till eight days after I conceived, if I did... scent last night/ this morning, I have felt nauseated, bloated and cramping.. I am a bit worried...
