Implantation bleeding?

[Wannabemumnz]

Hey lovely ladies so i am new to all this but i understand how a cycle works, So i had AF on the 28th of last month and will be due again in 2 days. Me and my partner DTD on day 13 of my cycle and almost instantly (2days) later i felt different, sore breasts (this is normal) but it felt different, also extremely emotional and have had horrible gas at night which i never get. Last night i noticed a tiny amount of light brown discharge after i wiped i automatically assumed that i would wake up today with AF even though its slightly early. Today i still have the same brown discharge with hints of red but nothing on my panties just when i wipe. Whats your opinion ladies? does this sound like implantation bleeding to you?
Thanks
