Helpppp - TTC xx

Hi everyone! Hoping someone could help as me and my partner are currently TTC, and it’s been around 3 months now. I came off the pill 26th October.

My last period was 19th Jan - 22nd Jan and I can suffer from really heavy periods, however I lightly bled on the 30th Jan for a couple days (I have never bled between my periods before). Since then I have been very bloated and had mild cramps on and off. I’ve had back ache but I also use to suffer from back ache so unsure whether it’s ‘new’. Also burping a lot! Me and my partner had sex last night, and for the first time I bled a little. It was only when I wiped that I noticed and it was really minimal - like spotting! I wore a pad today just incase, but nothing is on the pad, however when I go for a wee, I notice there is light bleeding on the tissue. Is this early stages of pregnancy???? Done a pregnancy test this morning and said negative but not sure if I’m testing too early?!

My period is due on the 16th Feb xxx (really sorry! TMI - I have attached a picture of the bleeding when I wipe just in case it helps)
