Just need some advice and support!

A little over a year ago I was around 19 weeks pregnant when i got a infection in my placenta that had spread to my blood from a rare virus that hasent been around since the 90's. The doctors tried antibiotics but it was already to late and they were worried I was going to go septic to they did a septic abortion. one of the hardest things I have ever had to go through but we have been trying on and off for some time now to get pregnant again with no luck. But recently my last period started off extremely heavy lasted two days than brown spotting for a day then little tiny drops of red for a day and a half. I have been having bad indigestion like I was with my last pregnancys and very light cramping since my period around two weeks ago i took a pregnancy test it came out nagative twice but i put it away under my counter to look at later and there was a slight positive line. But it was past the allotted time to look. I asked my doctor and he said its too early to tell and I cant find anything online does anyone have any advise for me.
