What do you think?

Hi! I've been TTC for 1.5 years now. Husband has low motility. He had surgery earlier this month for varicoceles. My cycles average 27 days. Day 27 for me was Friday. I spotted Thursday once. No aunt flow still. Brown spotting yesterday and today. Took a preg test today- negative. This happened to me in Sept where I missed my period and was 4 days late with no positive preg test. Day 5 I bled. 
Is this month going to be the same? Should I hold out hope? Help!!!!!
