Pregnancy/ pregacare

Hi I’m taking pregacare at the moment and my other half is on wellman we haven’t been on it for long maybe nearly a month and I don’t know how long it takes to work but my biggest problem is I’m bleeding quite a bit with a few blood clot looking blood and it’s confusing me like hell I don’t know what is going on I thought it would work not long af taking it a few days his sperm builds up a lot but all I see is light pinky redish brownish and heavyish looking blood on the pads normally I’m regular on my period but it’s one or two days before I’m due on. What is going on with my body am I pregnant and going through important bleeding or is it taking time and I’m going through early periods twice in a row?
