I'm not too sure when I ovulated as my period are irregular and also range in cycle lengths of up to 42 days... but My period should come in 2 weeks... Today I've started cramping and I've bled a little? At first I've was very very light and pink now it's like this... (pic attached in comment) just to add it's not filling my pad it's only when I wipe. I have had frequent intercourse the past 3/4 weeks so I'm unsure if this is implantation or a period??? I took a test this morning which was negative. Please tell me if this looks too heavy for implantation
