Just wondering

So, my husband and I have been trying for a while now. We've had several miscarriages and one tubal, its so hard after all that to continue to try but we really want a baby. My obgyn says I shouldn't have any problems conceiving but I'm not so sure about that. I have hypothyroidism and im anemic, so that doesnt help. This month i had a stomach virus that caused my period to be late, was supposed to be here one the 29th of May, i got sick the 30th and didn't start til tge 3rd of June. Usually my period is painful and heavy, but this month was different. It was extremely light and mostly brown and pink blood, there was one time it was kind of red like a normal period but not as dark. My periods usually last 4 to 5 days, but only lasted 3, even on here it shows only for 3 days. The 3rd thru the 5th. I have extreme discomfort with tampons and i usually dont, last night i put one in and was in so much pain i had to take it out, so i tried again and still not comfortable but i left it any way. This morning when i pulled it out, there was no blood what so ever. Im just wondering whats goin on.
