Help!

Ok... so I went to my Doctors appointment yesterday & I told her about some light cramping I’ve had on my right side. She pressed on it & said it was normal. (I just had my son 8 weeks ago.) Well last night I wiped and there was pink blood. (Yesterday started my fertile window.) Well today I woke up and was extremely light headed up until about an hour ago, and have had light pink blood when I wiped twice today. I also was throwing up. Is that normal for ovulating? I really hate to bother my doctor over nothing, but I’m really scared something is wrong. My son passed away the day he was born so we have been trying since about 5weeks PP, but I had a period 6 days ago. So I am just worried.
