Can an old spider bite affect a pregnacy?

6 months ago i was bitten by a brown recluse spider, at the time I was 5 weeks pregnant and the bite caused me to miscarrage a short time later. I am now 11 weeks pregnant and im really not well. I have 4 other children and there is something about this pregnacy that just doesnt feel right.. I was wondering if the venom could still be in my system causing me to feel very ill. There is a big difference between the morning sickness and me just not feeling right.. i cant think straight, i have the flu atm but it seems to be the worst i have ever had and i cant take any antibiotics to help me fight the infection... I have been getting some worrying pains in my stomack and wont be seeing a doctor for another week... I am really worried that the venom may still be running around in my system and may be affecting my unborn baby... any ideas?
