I need advice.....

I came off birthcontrol last August, and my husband and I have been trying since then.My last period was December the 23 it lasted 5 days. According to glow my period was suppose to start again the beginning of February ( due to my cycles ) I went to the doctor January 18th, he wanted a tested done, && it was negative. So I didnt think nothing about it. So I've been staying busy with crafts, and the mom life I forgot I was suppose to start. So I checked glow it said I was 6 days late. So I took a test it was negative, I waited a couple of days and I took another one it was negative. So I went to my doctor for my yearly feb 11th he wanted a test done but I think he forgot about it because he never called our posted them on my portal. I took another test this week and it showed another line but then went away and it showed negative. My doc said to wait a week and if I still haven't started call, but I'm thinking to wait till the end of this month just to see what will happen. I've been severely nauseated every other day or every day, I've died of heartburt on and off and I've had cramping like I wanna start but then I dont. Can someone help me, or give me advice on what to do.
