Should i be worried??

So my husband and I have been trying to have a baby for the past 2 years with no success! I have finally just given up and decided that if it happens it happens... well my last period was in April and we are now August and I haven’t paid a period in the month in between, which shocks me cause I’m always on time, but I did take 2 pregnancy test which they came out negative. In May when I should’ve started I only spotted and i never started, well for the past three days I’ve been only spotting in the morning and the rest of the day nothing. I’ve been lifting heavy stuff for the past days, so I don’t know if I should be worried and go to the doctor or hospital, just to confirm I’m not pregnant?? I just want to be sure and that way I can see what they can do for me since I haven’t had a period in 77 days... any input would be awesome! Thank you!
