I haven't had a period since April 23rd not sure if I have ovulated since but 2 days ago I had very light pink blood when I wiped and a little in my underwear. but have had nothing since could I possibly be pregnant? I don't want to test because last time I did I got a faint positive then negative. then went to the docs and got bloods and was negative and it was my thyroids but that's controlled by medication. so I'm not sure what to do as I'm scared. I'm TTC but scared I'm never going to be able too.
