Trying for another baby after a miscarraige

This is my first time writing publicly...

not sure how i should feel. I recently had a miscarriage sept 15,2019. I am already a mother of 5 all healthy babies. Me and my husband said we would try for one more. My last period was nov28. I took a first response on Christmas and the day after and had 3 positives but the lines were faint. And i took one today from the dollar store and it came out negative. I still have the nausea, bloating, gas, fatigue, moody, sob but no tender breast. Idk what to think or feel at this point. Not sure if i should be excited or not. I still have not started my period or even spotted.
