TTC, is this pregnancy? wantng my 1st BFP!!?

me and my husband has been ttc for a looooong time now. i have irregular cycles and have been having discharge on and off for 2 weeks and was spotting for on and off for 4 days(jus a spot here and a spot there on each day) but anyways so on one of those days i had bleeding after (TMI SRY) and horrible pounding headaches which really hurt now i have had some lower pubic area pains about an inch or 2 above my pubic/abdomen area and mostly on the left side but some on the right as well, is that normal? and i have not taken a test yet becuz i wanted to wait til monday so i could know it would be accurate.i Have very irregular menstruals (like 5 months apart) so im not sure when im suppost to have one. but i did have EWCM like almost 2 weeks ago. so im guessing that was ovulation. so the question is could i be pregnant and is it normal to bleed a spott or 2 after if i am pregnant? just by what i said i know yall aint doctors but i just needed some advice from people who have experienced this. thanks for answering all!!
