Hello! I was ovulating between 14th - 18th of this month (ish) I dtd on the 16th and 18th (without contraception). Haven't really had any symptoms as such apart from prominent purple veins on chest and boobs, just started to get headaches, had a very runny nose (cold) and watery CM (tmi), feeling VERY tired also feel very nauseous throughout most days. I have had some sharp pinching pains in my left side today on and off. Could this be implantation pains? I'm aware it's too early to test I'm just wondering what you all think! Could be luck be in??
