implant removal

becca • Mum to one beautiful girl💗 pregnant with baby #2💗 20💗

So i’ve had irregular periods most of my life, i had my implant taken out late november and i had a period on the 19th december for a week. Since then me and my partner started TTC for our second. My period was due 7 days ago and still hasn’t came/no signs of it coming but all my pregnancy tests are negative. Is this just a side effect from the implant removal? Should i see a doctor? Just looking for some advice :)
