Strange bleeding

I'm looking for input from people who have had similar exp please. Here's the dl. I'm 32, hv a 3 yr old dd, been ttc 15 months. Irregular ovulation and hubby's sperm hv morphology issues. Since approx march this yr I spot for 7/8 days, bleed for 3, and spot again for 3/4 days. I hv a 28 day cycle. Now this month I spotted for 7 days but it has completely stopped. I've been tired and moodier and hv tender bbs. Am I dreaming or cld I b pg? I'm going to wait a couple of days to test cos I've only got one left! Thanks ladies xox
