Light bleeding on/off 5 days + help!

Ladies!
Me & My partner have been TTC 14 months.
This time I started spotting/bleeding 3DPO ( enough to wear a pantyliner) and it lasted 5 days! (Which is Apprently unsual) It was smelly and i thought i might have an infection so ive gone to dr and got tests done but havent received the results yet. The smell went away and spotting stopped. Im 9DPO now and started spotting again! Slight cramps. AF due in 3-4 days. Im just freaking out. Ive been dissapointed so many times... Any of you experience anything similar?
